RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application Serial No. 60/129,391, filed Apr. 13, 1999, the entire teachings of which are incorporated herein by reference.

FIELD OF THE INVENTION

[0002] The present invention relates generally to isolated nucleic acids and the classification of the same. The invention more particularly relates to a novel gene and novel nucleic acids related to asthma and other respiratory diseases and the classification and therapeutic and diagnostic uses of this gene.

BACKGROUND

[0003] Mouse chromosome 2 has been linked to a variety of disorders including airway hyperesponsiveness and obesity (DeSanctis et al., Nature Genetics, 11: 150-154 (1995)); (Nagle et al, Nature, 398: 148-152 (1999)). This region of the mouse genome is homologous to portions of human chromosome 20 including 20p13-p12. Although human chromosome 20p13-12p has been linked to a variety of genetic disorders including diabetes insipidus, neurohypophyseal, congenital endothelial dystrophy of cornea, insomnia, neurodegeneration with brain iron accumulation 1 (Hallervorden-Spatz syndrome), fibrodysplasia ossificans progressiva, alagille syndrome, hydrometrocolpos (McKusick-Kaufman syndrome), Creutzfeldt-Jakob disease and Gerstmann-Straussler disease (See National Center for Biotechnology Information: http://www.ncbi.nlm.nih.gov/omim/), the genes affecting these disorders have yet to be discovered. There is a need in the art for identifying specific genes for such disorders because they are also associated with obesity, lung disease, particularly, inflammatory lung disease phenotypes such as Chronic Obstructive Lung Disease (COPD), Adult Respiratory Distress Syndrome (ARDS), and asthma. Identification and characterization of such genetic compositions will make possible the development of effective diagnostics and therapeutic means to treat lung related disorders.

SUMMARY OF THE INVENTION

[0004] This invention relates to Gene 216 located on chromosome 20p13-p12. Nucleic acids comprising all or a part of, or complementary fragments of Gene 216 and cDNA are described in various embodiments. Vectors and host cells containing the nucleic acids herein described are also included in this invention. These nucleic acids can be used in therapeutic applications for a multitude of diseases either through the overexpression of a recombinant nucleic acid comprising all or a portion of a Gene 216 gene, or by the use of these oligonucleotides and genes to modulate the expression of an endogenous gene or the activity of an endogenous gene product. Examples of therapeutic approaches include anti-sense inhibition of gene expression, gene therapy, monoclonal antibodies that specifically bind to the gene products, and the like. In vitro expression of the recombinant gene products can also be obtained.

[0005] Diagnostic methods are also described which utilize all or part of the nucleic acids of this invention. Such nucleic acids can be used, for example, as part of diagnostic methods to identify Gene 216 nucleic acids to screen for a predisposition to various genetic diseases. In addition, nucleic acids described herein can be used to identify chromosomal abnormalities within chromosomal regions 20p13-p12.

[0006] Further, this invention identifies various single nucleotide polymorphisms (SNPs) within several of the nucleic acids described herein. These polymorphisms also comprise changes to the polypeptides of the present invention. The SNPs, together with the wild-type alleles can be used to prepare specific probes for detection of various disease states in an individual. Thus, in one embodiment, this invention provides a method of detecting chromosome abnormalities on chromosome 20p13-p12.

[0007] Proteins, polypeptides, and peptides encoded by all or a part of the nucleic acids comprising Gene 216 are included in this invention. Such amino acid sequences are useful for diagnostic and therapeutic purposes. Further, antibodies can be raised against all or a part of these amino acid sequences for specific diagnostic and therapeutic methods requiring such antibodies. These antibodies can be polyclonal, monoclonal, or antibody fragments.

[0008] In a further embodiment, vectors and host cells containing vectors which comprise all or a portion of the nucleic acid sequences of this invention can be constructed for nucleic acid preparations, including anti-sense, and/or for expression of encoded proteins and polypeptides. Such host cells can be prokaryotic or eukaryotic cells.

[0009] Still another embodiment of the invention comprises a method of identifying a protein which is a candidate for being involved in asthma (a “candidate protein”). Candidate proteins are identified by a process comprising identifying a protein in a first individual having the asthma phenotype; (ii) identifying a protein in a second individual not having the asthma phenotype; comparing the protein of the first individual to the protein of the second individual, wherein (a) the protein that is present in the second individual but not the first individual is the candidate protein or (b) the protein that is present in a higher amount in the second individual than in the first individual is the candidate protein or (c) the protein that is present in a lower amount in the second individual than in the first individual is the candidate protein.

[0010] This invention also includes nonhuman transgenic animals containing one or more of the nucleic acids of this invention for screening and other purposes. Further, knockout nonhuman transgenic animals can be produced wherein one or more endogenous genes or portions of such genes corresponding to the nucleic acids of this invention are replaced by marker genes or are deleted.

DETAILED DESCRIPTION OF THE INVENTION

[0031] The present invention relates to Gene 216 nucleic acids comprising genomic DNA within BAC RPCI_(—)1098L22, the corresponding cDNA sequences, RNA, fragments of the genomic, cDNA, or RNA nucleic acids comprising 20, 40, 60, 100, 200, 500 or more contiguous nucleotides, and the complements thereof. Closely related variants are also included as part of this invention, as well as recombinant nucleic acids comprising at least 50, 60, 70, 80, or 90% of the nucleic acids described above which would be identical to a Gene 216 nucleic acids except for one or a few substitutions, deletions, or additions.

[0032] Further, the nucleic acids of this invention include the adjacent chromosomal regions of Gene 216 required for accurate expression of the respective gene. In a preferred embodiment, the present invention is directed to at least 15 contiguous nucleotides of the nucleic acid sequence of any of SEQ ID NO:1-SEQ ID NO:3. More particularly, embodiments of this invention include the BAC clone containing segments of Gene 216 including RPCI_(—)1098L22. A preferred embodiment is the nucleotide sequence of the BAC clones consisting of SEQ ID NO:7 (FIGS. 20A-20G).

[0033] This invention further relates to methods using isolated and/or recombinant nucleic acids (DNA or RNA) that are characterized by their ability to hybridize to (a) a nucleic acid encoding a protein or polypeptide, such as a nucleic acid having any of the sequences of SEQ ID NO:1-SEQ ID NO:3 or (b) a portion of the foregoing (e.g., a portion comprising the minimum nucleotides of the Gene 216 nucleic acid code a functional Gene 216 protein or the minimum number to inhibit an endogenous Gene 216; or by their ability to encode a polypeptide having the amino acid sequence of SEQ ID NO:4-SEQ ID NO:6, or to encode functional equivalents thereof; e.g., a polypeptide which when incorporated into a cell, has all or part of the activity of a Gene 216 protein, or by both characteristics. A functional equivalent of a Gene 216 protein, therefore, would have a similar amino acid sequence (at least 65% sequence identity) and similar characteristics to, or perform in substantially the same way as Gene 216 protein. A nucleic acid which hybridizes to a nucleic acid encoding a Gene 216 protein or polypeptide, such as SEQ ID NO:1-SEQ ID NO:3 can be double- or single-stranded. Hybridization to DNA such as DNA having the sequence SEQ ID NO:1-SEQ ID NO:3 includes hybridization to the strand shown or its complementary strand.

[0034] In one embodiment, the percent amino acid sequence similarity between a Gene 216 polypeptide such as SEQ ID NO:4-SEQ ID NO:6, and functional equivalents thereof is at least about 50%. In a preferred embodiment, the percent amino acid sequence similarity between such a Gene 216 polypeptide and its functional equivalents is at least about 65%. More preferably, the percent amino acid sequence similarity between a Gene 216 polypeptide and its functional equivalents is at least about 75%, and still more preferably, at least about 80%.

[0035] To determine percent nucleotide or amino acid sequence similarity, sequences can be compared to publicly available sequence databases (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov) using the blastn2 algorithm (Altsch, Nucl. Acids Res., 25:3389-3402 (1997)). The parameters for a typical search are: E=0.05, v=50, B=50 (where E is the expected probability score cutoff, V is the number of database entries returned in the reporting of the results, and B is the number of sequence alignments returned in the reporting of the results (Altsch et al, J. Mol. Biol., 215:403-410 (1990)).

[0036] Isolated and/or recombinant nucleic acids meeting these criteria comprise nucleic acids having sequences identical to sequences of naturally occurring Gene 216 genes such as Gene 216a, Gene 216b, Gene 216c, and portions thereof, or variants of the naturally occurring genes. Such variants include mutants differing by the addition, deletion or substitution of one or more nucleotides, modified nucleic acids in which one or more nucleotides are modified (e.g., DNA or RNA analogs), and mutants comprising one or more modified nucleotides including repeated fragments.

[0037] Such nucleic acids, including DNA or RNA, can be detected and isolated by hybridization under high stringency conditions or moderate stringency conditions, for example, which are chosen so as to not permit the hybridization of nucleic acids having non-complementary sequences. “Stringency conditions” for hybridizations is a term of art which refers to the conditions of temperature and buffer concentration which permit hybridization of a particular nucleic acid to another nucleic acid in which the first nucleic acid may be perfectly complementary to the second, or the first and second may share some degree of complementarity which is less than perfect. For example, certain high stringency conditions can be used which distinguish perfectly complementary nucleic acids from those of less complementarity. “High stringency conditions” and “moderate stringency conditions” for nucleic acid hybridizations are explained on pages 2.10.12.10.16 (see particularly 2.10.8-11) and pages 6.3.1-6 in Current Protocols in Molecular Biology (Ausubel, F. M. et al., eds., Vol. 1, containing supplements up through Supplement 29, 1995), the teachings of which are hereby incorporated by reference. The exact conditions which determine the stringency of hybridization depend not only on ionic strength, temperature and the concentration of destabilizing agents such as formamide, but also on factors such as the length of the nucleic acid sequence, base composition, percent mismatch between hybridizing sequences and the frequency of occurrence of subsets of that sequence within other non-identical sequences. Thus, high or moderate stringency conditions can be determined empirically.

[0038] High stringency hybridization procedures (1) employ low ionic strength and high temperature for washing, such as 0.015 M NaCl/0.0015 M sodium citrate, pH 7.0 (0.1×SSC) with 0.1% sodium dodecyl sulfate (SDS) at 50° C.; (2) employ during hybridization 50% (vol/vol) formamide with 5× Denhardt's solution (0.1% weight/volume highly purified bovine serum albumin/0.1% wt/vol Ficoll/0.1% wt/vol polyvinylpyrrolidone), 50 mM sodium phosphate buffer at pH 6.5 and 5×SSC at 42° C.; or (3) employ hybridization with 50% formamide, 5×SSC, 50 mM sodium phosphate (pH 6.8), 0.1% sodium pyrophosphate, 5× Denhardt's solution, sonicated salmon sperm DNA (50 μg/ml), 0.1% SDS, and 10% dextran sulfate at 42° C., with washes at 42° C. in 0.2×SSC and 0.1% SDS.

[0039] By varying hybridization conditions from a level of stringency at which no hybridization occurs to a level at which hybridization is first observed, conditions which will allow a given sequence to hybridize with the most similar sequences in the sample can be determined. Preferably the hybridizing sequences will have 60-70% sequence identity, more preferably 70-85% sequence identity, and even more preferably 90-100% sequence identity.

[0040] Exemplary conditions are described in Krause, M. H. and S. A. Aaronson (1991) Methods in Enzymology, 200:546-556. Also, see especially page 2.10.11 in Current Protocols in Molecular Biology (supra), which describes how to determine washing conditions for moderate or low stringency conditions. Washing is the step in which conditions are usually set so as to determine a minimum level of complementarity of the hybrids. Generally, from the lowest temperature at which only homologous hybridization occurs, a 1% mismatch between hybridizing nucleic acids results in a 1° C. decrease in the melting temperature T_(m), for any chosen SSC concentration. Generally, doubling the concentration of SSC results in an increase in T_(m) of ˜17° C. Using these guidelines, the washing temperature can be determined empirically for moderate or low stringency, depending on the level of mismatch sought.

[0041] Isolated and/or recombinant nucleic acids that are characterized by their ability to hybridize to (a) a nucleic acid encoding a Gene 216 polypeptide, such as the nucleic acids depicted as SEQ ID NO:1-SEQ ID NO:3, b) the complement, (c) or a portion of (a) or (b) (e.g. under high or moderate stringency conditions), may further encode a protein or polypeptide having at least one function characteristic of a Gene 216 polypeptide, such as proteolysis, adhesion, fusion, and intracellular activity, or binding of antibodies that also bind to non-recombinant Gene 216 protein or polypeptide. The catalytic or binding function of a protein or polypeptide encoded by the hybridizing nucleic acid may be detected by standard enzymatic assays for activity or binding (e.g., assays which measure the binding of a transit peptide or a precursor, or other components of the translocation machinery). Enzymatic assays, complementation tests, or other suitable methods can also be used in procedures for the identification and/or isolation of nucleic acids which encode a polypeptide such as a polypeptide of the amino acid sequences SEQ ID NO:4-SEQ ID NO:6, or a functional equivalent of this polypeptide. The antigenic properties of proteins or polypeptides encoded by hybridizing nucleic acids can be determined by immunological methods employing antibodies that bind to a Gene 216 polypeptide such as immunoblot, immunoprecipitation and radioimmunoassay. PCR methodology, including RAGE (Rapid Amplification of Genomic DNA Ends), can also be used to screen for and detect the presence of nucleic acids which encode Gene 216-like proteins and polypeptides, and to assist in cloning such nucleic acids from genomic DNA. PCR methods for these purposes can be found in Innis, M. A., et al. (1990) PCR Protocols: A Guide to Methods and Applications, Academic Press, Inc., San Diego, Calif., incorporated herein by reference.

[0042] It is understood that, as a result of the degeneracy of the genetic code, many nucleic acid sequences are possible which encode a Gene 216-like protein or polypeptide. Some of these will have little homology to the nucleotide sequences of any known or naturally-occurring Gene 216-like gene but can be used to produce the proteins and polypeptides of this invention by selection of combinations of nucleotide triplets based on codon choices. Such variants, while not hybridizable to a naturally-occurring Gene 216 gene, are contemplated within this invention.

[0043] The nucleic acids described herein are used in the methods of the present invention for production of proteins or polypeptides, through incorporation into cells, tissues, or organisms. In one embodiment, DNA containing all or part of the coding sequence for a Gene 216 polypeptide, or DNA which hybridizes to DNA having the sequence SEQ ID NO:1-SEQ ID NO:3, is incorporated into a vector for expression of the encoded polypeptide in suitable host cells. The encoded polypeptide consisting of Gene 216, or its functional equivalent is capable of normal activity, such as proteolysis, adhesion, fusion, and intracellular activity. The term “vector” as used herein refers to a nucleic acid molecule capable of replicating another nucleic acid to which it has been linked. A vector, for example, can be a plasmid.

[0044] Nucleic acids referred to herein as “isolated” are nucleic acids separated away from the nucleic acids of the genomic DNA or cellular RNA of their source of origin (e.g., as it exists in cells or in a mixture of nucleic acids such as a library), and may have undergone further processing. “Isolated”, as used herein, refers to nucleic or amino acid sequences that are at least 60% free, preferably 75% free, and most preferably 90% free from other components with which they are naturally associated. “Isolated” nucleic acids (polynucleotides) include nucleic acids obtained by methods described herein, similar methods or other suitable methods, including essentially pure nucleic acids, nucleic acids produced by chemical synthesis, by combinations of biological and chemical methods, and recombinant nucleic acids which are isolated. Nucleic acids referred to herein as “recombinant” are nucleic acids which have been produced by recombinant DNA methodology, including those nucleic acids that are generated by procedures which rely upon a method of artificial replication, such as the polymerase chain reaction (PCR) and/or cloning into a vector using restriction enzymes. “Recombinant” nucleic acids are also those that result from recombination events that occur through the natural mechanisms of cells, but are selected for after the introduction to the cells of nucleic acids designed to allow or make probable a desired recombination event. Portions of the isolated nucleic acids which code for polypeptides having a certain function can be identified and isolated by, for example, the method of Jasin, M., et al., U.S. Pat. No. 4,952,501.

[0045] A further embodiment of the invention is antisense nucleic acids or oligonucleotides which are complementary, in whole or in part, to a target molecule comprising a sense strand, and can hybridize with the target molecule. The target can be DNA, or its RNA counterpart (i.e., wherein T residues of the DNA are U residues in the RNA counterpart). When introduced into a cell, antisense nucleic acids or oligonucleotides can inhibit the expression of the gene encoded by the sense strand or the mRNA transcribed from the sense strand. Antisense nucleic acids can be produced by standard techniques. See, for example, Shewmaker, et al., U.S. Pat. No. 5,107,065.

[0046] In a particular embodiment, an antisense nucleic acid or oligonucleotide is wholly or partially complementary to and can hybridize with a target nucleic acid (either DNA or RNA), wherein the target nucleic acid can hybridize to a nucleic acid having the sequence of the complement of the strand in SEQ ID NO:1-SEQ ID NO:3. For example, an antisense nucleic acid or oligonucleotide can be complementary to a target nucleic acid having the sequence shown as the strand of the open reading frame of SEQ ID NO:1-SEQ ID NO:3 or nucleic acid encoding a functional equivalent of Gene 216, or to a portion of these nucleic acids sufficient to allow hybridization. A portion, for example a sequence of 16 nucleotides, could be sufficient to inhibit expression of the protein. Or, an antisense nucleic acid or oligonucleotide, complementary to 5′ or 3′ untranslated regions, or overlapping the translation initiation codon (5′ untranslated and translated regions), of the Gene 216 gene, or a gene encoding a functional equivalent can also be effective. In another embodiment, the antisense nucleic acid is wholly or partially complementary to and can hybridize with a target nucleic acid which encodes a Gene 216 polypeptide.

[0047] In addition to the antisense nucleic acids of the invention, oligonucleotides can be constructed which will bind to duplex nucleic acid either in the gene or the DNA:RNA complex of transcription, to form a stable triple helix-containing or triplex nucleic acid to inhibit transcription and/or expression of a gene encoding Gene 216, or its functional equivalent (Frank-Kamenetskii, M. D. and Mirkin, S. M. (1995) Ann. Rev. Biochem. 64:65-95.) Such oligonucleotides of the invention are constructed using the base-pairing rules of triple helix formation and the nucleotide sequence of the gene or mRNA for Gene 216. These oligonucleotides can block Gene 216-type activity in a number of ways, including prevention of transcription of the Gene 216 gene or by binding to mRNA as it is transcribed by the gene.

[0048] The invention also relates to proteins or polypeptides encoded by the novel nucleic acids described herein. The proteins and polypeptides of this invention can be isolated and/or recombinant. Proteins or polypeptides referred to herein as “isolated” are proteins or polypeptides purified to a state beyond that in which they exist in cells. In a preferred embodiment, they are at least 10% pure; i.e., most preferably they are substantially purified to 80 or 90% purity. “Isolated” proteins or polypeptides include proteins or polypeptides obtained by methods described infra, similar methods or other suitable methods, and include essentially pure proteins or polypeptides, proteins or polypeptides produced by chemical synthesis or by combinations of biological and chemical methods, and recombinant proteins or polypeptides which are isolated. Proteins or polypeptides referred to herein as “recombinant” are proteins or polypeptides produced by the expression of recombinant nucleic acids.

[0049] In a preferred embodiment, the protein or portion thereof has at least one function characteristic of a Gene 216 protein or polypeptide, for example, proteolysis, adhesion, fusion, and intracellular activity in the case of Gene 216 analogs, and/or antigenic function (e.g., binding of antibodies that also bind to naturally occurring Gene 216 polypeptide). As such, these proteins are referred to as analogs, and include, for example, naturally occurring Gene 216, variants (e.g. mutants) of those proteins and/or portions thereof. Such variants include mutants differing by the addition, deletion or substitution of one or more amino acid residues, or modified polypeptides in which one or more residues are modified, and mutants comprising one or more modified residues. The variant can have “conservative” changes, wherein a substituted amino acid has similar structural or chemical properties, e.g., replacement of leucine with isoleucine. More infrequently, a variant can have “nonconservative” changes, e.g., replacement of a glycine with a tryptophan. Guidance in determining which amino acid residues can be substituted, inserted, or deleted without abolishing biological or immunological activity can be found using computer programs well known in the art, for example, DNASTAR software (DNASTAR, Inc., Madison, Wis. 53715 U.S.A.).

[0050] A “portion” as used herein with regard to a protein or polypeptide, refers to fragments of that protein or polypeptide. The fragments can range in size from 5 amino acid residues to all but one residue of the entire protein sequence. Thus, a portion or fragment can be at least 5, 5-50, 50-100, 100-200, 200-400, 400-800, or more consecutive amino acid residues of a Gene 216 protein or polypeptide, for example, SEQ ID NO:4-SEQ ID NO:6, or a variant thereof.

[0051] The invention also relates to isolated, synthesized and/or recombinant portions or fragments of a Gene 216 protein or polypeptide as described above. Polypeptide fragments of the enzyme can be made which have full or partial function on their own, or which when mixed together (though fully, partially, or nonfunctional alone), spontaneously assemble with one or more other polypeptides to reconstitute a functional protein having at least one functional characteristic of a Gene 216 protein of this invention.

[0052] The invention also concerns the use of the nucleotide sequence of the nucleic acids of this invention to identify DNA probes for Gene 216 genes, PCR primers to amplify Gene 216 genes, nucleotide polymorphisms in Gene 216 genes, and regulatory elements of the Gene 216 genes.

[0053] Gene 216 was isolated by narrowly defining the region of chromosome 20p13-p12 which was associated with airway hyperresponsiveness, asthma and atopy. Gene 216 is also important in other diseases such as obesity and thus, there was a need to identify and isolate the gene.

[0054] To aid in the understanding of the specification and claims, the following definitions are provided.

[0055] “Disorder region” refers to a portion of the human chromosome 20 bounded by the markers D20S502 and D20S851. A “disorder-associated” nucleic acid or polypeptide sequence “derived from” refers to a nucleic acid sequence that maps to region 20p13-p12 and polypeptides encoded therein. For nucleic acid sequences, this encompasses sequences that are homologous or complementary to the sequence, as well as “sequence-conservative variants” and “function-conservative variants.” For polypeptide sequences, this encompasses “function-conservative variants.” Included are naturally-occurring mutations causative of respiratory diseases or obesity, such as but not limited to mutations which cause inappropriate expression (e.g., lack of expression, overexpression, expression in an inappropriate tissue type). “Sequence-conservative” variants are those in which a change of one or more nucleotides in a given codon position results in no alteration in the amino acid encoded at that position. “Function-conservative” variants are those in which a change in one or more nucleotides in a given codon position results in a polypeptide sequence in which a given amino acid residue in a polypeptide has been changed without substantially altering the overall conformation and function of the native polypeptide, including, but not limited to, replacement of an amino acid with one having similar physico-chemical properties (such as, for example, acidic, basic, hydrophobic, and the like). “Function-conservative” variants also include analogs of a given polypeptide and any polypeptides that have the ability to elicit antibodies specific to a designated polypeptide.

[0056] “Nucleic acid or “polynucleotide” as used herein refers to purine- and pyrimidine-containing polymers of any length, either polyribonucleotides or polydeoxyribonucleotide or mixed polyribo-polydeoxyribo nucleotides. This includes single- and double-stranded molecules, i.e., DNA-DNA, DNA-RNA and RNA-RNA hybrids, as well as “protein nucleic acids” (PNA) formed by conjugating bases to an amino acid backbone. This also includes nucleic acids containing modified bases.

[0057] A “coding sequence” or a “protein-coding sequence” is a polynucleotide sequence capable of being transcribed into mRNA and/or capable of being translated into a polypeptide. The boundaries of the coding sequence are typically determined by a translation start codon at the 5′-terminus and a translation stop codon at the 3′-terminus.

[0058] A “complement” of a nucleic acid sequence as used herein refers to the “antisense” sequence that participates in Watson-Crick base-pairing with the original sequence.

[0059] A “probe” refers to a nucleic acid or oligonucleotide that forms a hybrid structure with a sequence in a target region due to complementarily of at least one sequence in the probe with a sequence in the target region.

[0060] Nucleic acids are “hybridizable” to each other when at least one strand of nucleic acid can anneal to another nucleic acid strand under defined stringency conditions. As is well known in the art, stringency of hybridization is determined, e.g., by (a) the temperature at which hybridization and/or washing is performed, and (b) the ionic strength and polarity (e.g., formamide) of the hybridization and washing solutions, as well as other parameters. Hybridization requires that the two nucleic acids contain substantially complementary sequences; depending on the stringency of hybridization, however, mismatches may be tolerated. The appropriate stringency for hybridizing nucleic acids depends on the length of the nucleic acids and the degree of complementarily, variables well known in the art.

[0061] An “immunogenic component”, is a moiety that is capable of eliciting a humoral and/or cellular immune response in a host animal.

[0062] An “antigenic component” is a moiety that binds to its specific antibody with sufficiently high affinity to form a detectable antigen-antibody complex.

[0063] A “sample” as used herein refers to a biological sample, such as, for example, tissue or fluid isolated from an individual (including without limitation plasma, serum, cerebrospinal fluid, lymph, tears, saliva, milk, pus, and tissue exudates and secretions) or from in vitro cell culture constituents, as well as samples obtained from e.g., a laboratory procedure.

[0064] “Gene” refers to a DNA sequence that encodes through its template or messenger RNA a sequence of amino acids characteristic of a specific peptide, polypeptide or protein. The term “gene” as used herein with reference to genomic DNA includes intervening, non-coding regions, as well as regulatory regions, and can include 5′ and 3′ ends.

[0065] “Gene sequence” refers to a DNA molecule, including both a DNA molecule which contains a non-transcribed or non-translated sequence. The term is also intended to include any combination of gene(s), gene fragment(s), non-transcribed sequence(s) or non-translated sequence(s) which are present on the same DNA molecule.

[0066] A gene sequence is “wild-type” if such sequence is usually found in individuals unaffected by the disease or condition of interest. However, environmental factors and other genes can also play an important role in the ultimate determination of the disease. In the context of complex diseases involving multiple genes (“oligogenic disease”), the “wild type” or normal sequence can also be associated with a measurable risk or susceptibility, receiving its reference status based on its frequency in the general population.

[0067] A gene sequence is a “mutant” sequence if it differs from the wild-type sequence. In some cases, the individual carrying such gene has increased susceptibility toward the disease or condition of interest. In other cases, the “mutant” sequence might also refer to a sequence that decreases the susceptibilty toward a disease or condition of interest, and thus acting in a protective manner. Also a gene is a “mutant” gene if too much (“overexpressed”) or too little (“underexpressed”) of such gene is expressed in the tissues in which such gene is normally expressed, thereby causing the disease or condition of interest.

[0068] A gene sequence is a “variant” sequence if it is substantially similar in structure to either the entire gene or to a fragment of the gene. Both wild-type genes and mutant genes have variant sequences.

[0069] The sequences of the present invention may be derived from a variety of sources including DNA, cDNA, synthetic DNA, synthetic RNA or combinations thereof. Such sequences may comprise genomic DNA which may or may not include naturally occurring introns. Moreover, such genomic DNA may be obtained in association with promoter regions or poly (A) sequences. The sequences, genomic DNA or cDNA may be obtained in any of several ways. Genomic DNA can be extracted and purified from suitable cells by means well known in the art. Alternatively, mRNA can be isolated from a cell and used to produce cDNA by reverse transcription or other means.

[0070] “cDNA” refers to complementary or copy DNA produced from an RNA template by the action of RNA-dependent DNA polymerase (reverse transcriptase). Thus, a “cDNA clone” means a duplex DNA sequence complementary to an RNA molecule of interest, carried in a cloning vector or PCR amplified. This term includes genes from which the intervening sequences have been removed.

[0071] “Recombinant DNA” means a molecule that has been recombined by in vitro splicing/and includes cDNA or a genomic DNA sequence.

[0072] “Cloning” refers to the use of in vitro recombination techniques to insert a particular gene or other DNA sequence into a vector molecule. In order to successfully clone a desired gene, it is necessary to use methods for generating DNA fragments, for joining the fragments to vector molecules, for introducing the composite DNA molecule into a host cell in which it can replicate, and for selecting the clone having the target gene from amongst the recipient host cells.

[0073] “cDNA library” refers to a collection of recombinant DNA molecules containing cDNA inserts which together comprise the entire genome of an organism. Such a cDNA library can be prepared by methods known to one skilled in the art and described by, for example, Cowell and Austin, “cDNA Library Protocols,” Methods in Molecular Biology (1997). Generally, RNA is first isolated from the cells of an organism from whose genome it is desired to clone a particular gene.

[0074] “Cloning vehicle” refers to a plasmid or phage DNA or other DNA sequence which is able to replicate in a host cell. The cloning vehicle is characterized by one or more endonuclease recognition sites at which such DNA sequences may be cut in a determinable fashion without loss of an essential biological function of the DNA, which may contain a marker suitable for use in the identification of transformed cells.

[0075] “Expression control sequence” refers to a sequence of nucleotides that control or regulate expression of structural genes when operably linked to those genes. These include, for example, the lac systems, the trp system, major operator and promoter regions of the phage lambda, the control region of fd coat protein and other sequences known to control the expression of genes in prokaryotic or eukaryotic cells. Expression control sequences will vary depending on whether the vector is designed to express the operably linked gene in a prokaryotic or eukaryotic host, and may contain transcriptional elements such as enhancer elements, termination sequences, tissue-specificity elements and/or translational initiation and termination sites.

[0076] “Expression vehicle” refers to a vehicle or vector similar to a cloning vehicle but which is capable of expressing a gene which has been cloned into it, after transformation into a host. The cloned gene is usually placed under the control of (i.e., operably linked to) an expression control sequence.

[0077] “Operably linked” means that the promoter controls the initiation of expression of the gene. A promoter is operably linked to a sequence of proximal DNA if upon introduction into a host cell the promoter determines the transcription of the proximal DNA sequence(s) into one or more species of RNA. A promoter is operably linked to a DNA sequence if the promoter is capable of initiating transcription of that DNA sequence.

[0078] “Host” includes prokaryotes and eukaryotes. The term includes an organism or cell that is the recipient of a replicable expression vehicle.

[0079] “Amplification of nucleic acids” refers to methods such as polymerase chain reaction (PCR), ligation amplification (or ligase chain reaction, LCR) and amplification methods based on the use of Q-beta replicase. These methods are well known in the art and described, for example, in U.S. Pat. Nos. 4,683,195 and 4,683,202. Reagents and hardware for conducting PCR are commercially available. Primers useful for amplifying sequences from the disorder region are preferably complementary to, and preferably hybridize specifically to, sequences in the 20p13-p12 region or in regions that flank a target region therein. Gene 216 generated by amplification may be sequenced directly. Alternatively, the amplified sequence(s) may be cloned prior to sequence analysis.

[0080] “Antibodies” refer to polyclonal and/or monoclonal antibodies and fragments thereof, and immunologic binding equivalents thereof, that can bind to asthma proteins and fragments thereof or to nucleic acid sequences from the 20p13-p12 region, particularly from the asthma locus or a portion thereof. The term antibody is used both to refer to a homogeneous molecular entity, or a mixture such as a serum product made up of a plurality of different molecular entities. Proteins may be prepared synthetically in a protein synthesizer and coupled to a carrier molecule and injected over several months into rabbits. Rabbit sera is tested for immunoreactivity to the protein or fragment. Monoclonal antibodies may be made by injecting mice with the proteins, or fragments thereof. Monoclonal antibodies will be screened by ELISA and tested for specific immunoreactivity with protein or fragments thereof. (Harlow et al, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1988.) These antibodies will be useful assays as well as pharmaceuticals.

[0081] A nucleic acid or fragment thereof is “substantially homologous” or “substantially similar” to another if, when optimally aligned (with appropriate nucleotide insertions and/or deletions) with the other nucleic acid (or its complementary strand), there is nucleotide sequence identity in at least about 60% of the nucleotide bases, usually at least about 70%, more usually at least about 80%, preferably at least about 90%, and more preferably at least about 95-98% of the nucleotide bases.

[0082] Alternatively, substantial homology or similarity exists when a nucleic acid or fragment thereof will hybridize, under selective hybridization conditions, to another nucleic acid (or a complementary strand thereof). Selectivity of hybridization exists when hybridization which is substantially more selective than total lack of specificity occurs. Typically, selective hybridization will occur when there is at least about 55% homology over a stretch of at least about nine or more nucleotides, preferably at least about 65%, more preferably at least about 75%, and most preferably at least about 90%. (See, Kanehisa, [CITE] 1984.) The length of homology comparison, as described, may be over longer stretches, and in certain embodiments will often be over a stretch of at least about 14 nucleotides, usually at least about 20 nucleotides, more usually at least about 24 nucleotides, typically at least about 28 nucleotides, more typically at least about 32 nucleotides, and preferably at least about 36 or more nucleotides.

Standard reference works setting forth the general principles of immunology include Sell, S., Immunology, Immunopathology & Immunity, 5th Ed., Appleton & Lange, Publ., Stamford, Conn. (1996); Male, D., et al., Advanced Immunology, 3d Ed., Times Mirror Int'l Publishers Ltd., Publ., London (1996); Stites, D. P., and Terr, A.

(1991). Any suitable materials and/or methods known to those of skill can be utilized in carrying out the present invention; however, preferred materials and/or methods are described. Materials, reagents and the like to which reference is made in the following description and examples are obtainable from commercial sources, unless otherwise noted.

[0084] The nucleic acids of the invention may be isolated directly from cells. Alternatively, the polymerase chain reaction (PCR) method can be used to produce the nucleic acids of the invention, using either chemically synthesized strands or genomic material as templates. Primers used for PCR can be synthesized using the sequence information provided herein and can further be designed to introduce appropriate new restriction sites, if desirable, to facilitate incorporation into a given vector for recombinant expression.

[0085] The invention also provides vectors comprising the disorder-associated sequences or derivatives or fragments thereof and host cells for the production of purified proteins. A large number of vectors, including plasmid and fungal vectors, have been described for replication and/or expression in a variety of eukaryotic and prokaryotic hosts, and may be used for gene therapy as well as for simple cloning or protein expression.

[0086] Using the information provided in SEQ ID NO:1-SEQ ID NO:3, one skilled in the art will be able to clone and sequence all representative nucleic acids of interest, including nucleic acids encoding complete protein-coding sequences. It is to be understood that non-protein-coding sequences contained within SEQ ID NO:1-SEQ ID NO:3 and the genomic sequence of SEQ ID NO:7 (FIGS. 20A-20G) are also within the scope of the invention. Such sequences include, without limitation, sequences important for replication, recombination, transcription and translation. Non-limiting examples include promoters and regulatory binding sites involved in regulation of gene expression, and 5′- and 3′-untranslated sequences (e.g., ribosome-binding sites) that form part of mRNA molecules.

[0087] The nucleic acids of the present invention find use as primers and templates for the recombinant production of disorder-associated peptides or polypeptides, for chromosome and gene mapping, to provide antisense sequences, for tissue distribution studies, to locate and obtain full length genes, to identify and obtain homologous sequences (wild-type and mutants), and in diagnostic applications.

[0088] Polypeptides according to the invention are at least five or more residues in length. Preferably, the polypeptides comprise at least about 12, more preferably at least about 20 and most preferably at least about 30 such residues. Nucleic acids comprising protein-coding sequences can be used to direct the expression of asthma-associated polypeptides in intact cells or in cell-free translation systems. The known genetic code, tailored if desired for more efficient expression in a given host organism, can be used to synthesize oligonucleotides encoding the desired amino acid sequences. The resulting oligonucleotides can be inserted into an appropriate vector and expressed in a compatible host organism.

[0089] The polypeptides of the present invention, including function-conservative variants, may be isolated from wild-type or mutant cells, or from heterologous organisms or cells (e.g., bacteria, fungi, yeast, insect, plant, and mammalian cells) in which an disorder-associated protein-coding sequence has been introduced and expressed. Furthermore, the polypeptides may be part of recombinant fusion proteins. The polypeptides can also, advantageously, be made using cell-free protein synthesis systems or by synthetic chemistry. Polypeptides may be chemically synthesized by commercially available automated procedures, including, without limitation, exclusive solid phase synthesis, partial solid phase methods, fragment condensation or classical solution synthesis.

[0090] Methods for polypeptide purification are well-known in the art, including, without limitation, preparative disc-gel electrophoresis, isoelectric focusing, HPLC, reversed-phase HPLC, gel filtration, ion exchange and partition chromatography, and countercurrent distribution. For some purposes, it is preferable to produce the polypeptide in a recombinant system in which the disorder-associated protein contains an additional sequence tag that facilitates purification. Alternatively, antibodies produced against an disorder-associated protein or against peptides derived therefrom can be used as purification reagents. Other purification methods are possible.

[0091] The present invention also encompasses derivatives and homologies of disorder-associated polypeptides. For some purposes, nucleic acid sequences encoding the peptides may be altered by substitutions, additions, or deletions that provide for functionally equivalent molecules, i.e., function-conservative variants.

[0092] The isolated polypeptides may be modified by, for example, phosphorylation, sulfation, acylation, or other protein modifications. They may also be modified with a label capable of providing a detectable signal, either directly or indirectly, including, but not limited to, radioisotopes and fluorescent compounds.

[0093] Both the naturally occurring and recombinant forms of the polypeptides of the invention can advantageously be used to screen compounds for binding activity. Many methods of screening for binding activity are known by those skilled in the art and may be used to practice the invention. Several methods of automated assays have been developed in recent years so as to permit screening of tens of thousands of compounds in a short period of time. Such high-throughput screening methods are particularly preferred. The use of high-throughput screening assays to test for inhibitors is greatly facilitated by the availability of large amounts of purified polypeptides, as provided by the invention. The polypeptides of the invention also find use as therapeutic agents as well as antigenic components to prepare antibodies.

[0094] The polypeptides of this invention find use as immunogenic components useful as antigens for preparing antibodies by standard methods. It is well known in the art that immunogenic epitopes generally contain at least about five amino acid residues, Ohno et al. 1985, Proc. Natl. Acad. Sci. USA 82:2945. Therefore, the immunogenic components of this invention will typically comprise at least five amino acid residues of the sequence of the complete polypeptide chains. Preferably, they will contain at least 7, and most preferably at least about 10 amino acid residues or more to ensure that they will be immunogenic. Whether a given component is immunogenic can readily be determined by routine experimentation Such immunogenic components can be produced by proteolytic cleavage of larger polypeptides or by chemical synthesis or recombinant technology and are thus not limited by proteolytic cleavage sites. The present invention thus encompasses antibodies that specifically recognize asthma-associated immunogenic components.

[0095] Antibodies according to the present invention include polyclonal and monoclonal antibodies. The antibodies may be elicited in an animal host by immunization with disorder-associated immunogenic components or may be formed by in vitro immunization (sensitization) of immune cells. The immunogenic components used to elicit the production of antibodies may be isolated from cells or chemically synthesized. The antibodies may also be produced in recombinant systems programmed with appropriate antibody-encoding DNA. Alternatively, the antibodies may be constructed by biochemical reconstitution of purified heavy and light chains. The antibodies include hybrid antibodies, chimeric antibodies, and univalent antibodies. Also included are Fab fragments, including Fab¹ and Fab(ab)² fragments of antibodies.

[0096] These antibodies, whether polyclonal or monoclonal, can be used, e.g., in an immobilized form bound to a solid support by well known methods, to purify the immunogenic components and disorder-associated polypeptides by immunoaffinity chromatography. Antibodies against the immunogenic components can also be used, unlabeled or labeled by standard methods, as the basis for immunoassays, i.e., as diagnostic reagents.

[0097] Hybridomas of the invention used to make monoclonal antibodies against the immunogenic components of the invention are produced by well-known techniques. Usually, the process involves the fusion of an immortalizing cell line with a B-lymphocyte that produces the desired antibody. Alternatively, non-fusion techniques for generating immortal antibody-producing cell lines are possible, and come within the purview of the present invention, e.g., virally-induced transformation, Casali et al., 1986, Science 234:476. Immortalizing cell lines are usually transformed mammalian cells, particularly myeloma cells of rodent, bovine, and human origin. Most frequently, rat or mouse myeloma cell lines are employed as a matter of convenience and availability.

[0098] Hybridomas are selected by standard procedures, such as HAT (hypoxanthine-aminopterin-thymidine) selection. From among these hybridomas, those secreting the desired antibody are selected by assaying their culture medium by standard immunoassays, such as Western blotting, ELISA (enzyme-linked immunosorbent assay), RtA (radioimmunoassay), or the like. Antibodies are recovered from the medium using standard protein purification techniques, Tijssen, 1985, Practice and Theory of Enzyme Immunoassays, Elsevier, Amsterdam.

[0099] I. Localization of an Asthma Locus on Chromosome 20p13-p12 and the Characterization of a Candidate Gene Within the Region

[0100] To identify genes in the region on 20p13-p12, a set of bacterial artificial chromosome(BAC) clones containing this chromosomal region was identified. The BAC clones served as a template for genomic DNA sequencing and serve as reagents for identifying coding sequences by direct cDNA selection. Genomic sequencing and direct cDNA selection were used to characterize DNA from 20p13-p12.

[0101] When a gene has been genetically localized to a specific chromosomal region, the genes in this region can be characterized at the molecular level by a series of steps that include: cloning of the entire region of DNA in a set of overlapping clones (physical mapping), characterization of genes encoded by these clones by a combination of direct cDNA selection, exon trapping and DNA sequencing (gene identification), and identification of mutations in these genes by comparative DNA sequencing of affected and unaffected members of the kindred and/or in unrelated affected individuals and unrelated unaffected controls (mutation analysis).

[0102] Physical mapping is accomplished by screening libraries of human DNA cloned in vectors that are propagated in a host such as E. coli, using hybridization or PCR assays from unique molecular landmarks in the chromosomal region of interest. To generate a physical map of the disorder region, a library of human DNA cloned in BACs was screened with a set overgo markers that had been previously mapped to chromosome 20p13-p12 by the efforts of the Human Genome Project. Overgos are unique molecular landmarks in the human genome that can be assayed by hybridization. Through the combined efforts of the Human Genome Project, the location of thousands of overgos on the twenty-two autosomes and two sex chromosomes has been determined. For a positional cloning effort, the physical map is tied to the genetic map because the markers used for genetic mapping can also be used as overgos for physical mapping. By screening a BAC library with a combination of overgos derived from genetic markers, genes, and random DNA fragments, a physical map comprised of overlapping clones representing all of the DNA in a chromosomal region of interest can be assembled.

[0103] BACs are cloning vectors for large (80 kilobase to 200 kilobase) segments of human or other DNA that are propagated in E. coli. To construct a physical map using BACs, a library of BAC clones is screened so that individual clones harboring the DNA sequence corresponding to a given overgo or set of overgos are identified. Throughout most of the human genome, the overgo markers are spaced approximately 20 to 50 kilobases apart, so that an individual BAC clone typically contains at least two overgo markers. In addition, the BAC libraries that were screened contain enough cloned DNA to cover the human genome twelve times over. Therefore, an individual overgo typically identifies more than one BAC clone. By screening a twelve-fold coverage BAC library with a series of overgo markers spaced approximately 50 kilobases apart, a physical map consisting of a series of overlapping contiguous BAC clones, i.e., BAC “contigs,” can be assembled for any region of the human genome. This map is closely tied to the genetic map because many of the overgo markers used to prepare the physical map are also genetic markers.

[0104] When constructing a physical map, it often happens that there are gaps in the overgo map of the genome that result in the inability to identify BAC clones that are overlapping in a given location. Typically, the physical map is first constructed from a set of overgos identified through the publicly available literature and World Wide Web resources. The initial map consists of several separate BAC contigs that are separated by gaps of unknown molecular distance. To identify BAC clones that fill these gaps, it is necessary to develop new overgo markers from the ends of the clones on either side of the gap. This is done by sequencing the terminal 200 to 300 base pairs of the BACs flanking the gap, and developing a PCR or hybridization based assay. If the terminal sequences are demonstrated to be unique within the human genome, then the new overgo can be used to screen the BAC library to identify additional BACs that contain the DNA from the gap in the physical map. To assemble a BAC contig that covers a region the size of the disorder region (6,000,000 or more base pairs), it is necessary to develop new overgo markers from the ends of a number of clones.

[0105] After building a BAC contig, this set of overlapping clones serves as a template for identifying the genes encoded in the chromosomal region. Gene identification can be accomplished by many methods. Three methods are commonly used: (1) a set of BACs selected from the BAC contig to represent the entire chromosomal region can be sequenced, and computational methods can be used to identify all of the genes, (2) the BACs from the BAC contig can be used as a reagent to clone cDNAs corresponding to the genes encoded in the region by a method termed direct cDNA selection, or (3) the BACs from the BAC contig can be used to identify coding sequences by selecting for specific DNA sequence motifs in a procedure called exon trapping. The present invention includes Gene 216 identified by the first two methods.

[0106] To sequence the entire BAC contig representing the disorder region, a set of BACs can be chosen for subcloning into plasmid vectors and subsequent DNA sequencing of these subclones. Since the DNA cloned in the BACs represents genomic DNA, this sequencing is referred to as genomic sequencing to distinguish it from cDNA sequencing. To initiate the genomic sequencing for a chromosomal region of interest, several non-overlapping BAC clones are chosen. DNA for each BAC clone is prepared, and the clones are sheared into random small fragments which are subsequently cloned into standard plasmid vectors such as pUC18. The plasmid clones are then grown to propagate the smaller fragments, and these are the templates for sequencing. To ensure adequate coverage and sequence quality for the BAC DNA sequence, sufficient plasmid clones are sequenced to yield three-fold coverage of the BAC clone. For example, if the BAC is 100 kilobases long, then phagemids are sequenced to yield 300 kilobases of sequence. Since the BAC DNA was randomly sheared prior to cloning in the phagemid vector, the 300 kilobases of raw DNA sequence can be assembled by computational methods into overlapping DNA sequences termed sequence contigs. For the purposes of initial gene identification by computational methods, three-fold coverage of each BAC is sufficient to yield twenty to forty sequence contigs of 1000 base pairs to 20,000 base pairs.

[0107] The sequencing strategy employed in this invention was to initially sequence “seed” BACs from the BAC contig in the disorder region. The sequence of the “seed” BACs was then used to identify minimally overlapping BACs from the contig, and these were subsequently sequenced. In this manner, the entire candidate region can be sequenced, with several small sequence gaps left in each BAC. This sequence serves as the template for computational gene identification. One method for computational gene identification is to compare the sequence of BAC contig to publicly available databases of cDNA and genomic sequences, e.g. unigene, dbEST, genbank. These comparisons are typically done using the BLAST family of computer algorithms and programs (Altshul et al, J. Mol. Biol., 215:403-410 (1990)). The BAC sequence can also be translated into protein sequence, and the protein sequence can be used to search publicly available protein databases, using a version of BLAST designed to analyze protein sequences (Altshul et al, Nucl. Acids Res., 25:3389-3402 (1997)). Another method is to use computer algorithms such as MZEF (Zhang, Proc. Natl. Acad. Sci., 94:565-568 (1997)), GRAIL (Uberbacher et al, Methods Enzymol., 266:259-281 (1996)), and Genscan (Burge and Karlin, J. Mol. Biol., 268:78-94) which predicts the location of exons in the sequence based on the presence of specific DNA sequence motifs that are common to all exons, as well as the presence of codon usage typical of human protein encoding sequences.

[0108] In addition to identifying genes by computational methods, genes were also identified by direct cDNA selection (Del Mastro and Lovett, Methods in Molecular Biology, Humana Press Inc., NJ (1996)). In direct cDNA selection, cDNA pools from tissues of interest are prepared, and BACs from the candidate region are used in a liquid hybridization assay to capture the cDNAs which base pair to coding regions in the BAC. In the methods described herein, the cDNA pools were created from several different tissues by random priming and oligo dT priming the first strand cDNA from polyA RNA, synthesizing the second strand cDNA by standard methods, and adding linkers to the ends of the cDNA fragments. The linkers are used to amplify the c-DNA pools BAC clones from the disorder region identified by screening the RPCI-11 BAC library (P. deJong, Russell Park Cancer Institute) were used as a template for initiating DNA synthesis to create a biotin labeled copy of BAC DNA. The biotin labelled copy of the BAC DNA is then denatured and incubated with an excess of the PCR amplified, Tinkered cDNA pools which have also been denatured. The BAC DNA and cDNA are allowed to anneal in solution, and heteroduplexes between the BAC and the cDNA are isolated using streptavidin coated magnetic beads. The cDNAs that are captured by the BAC are then amplified using primers complimentary to the linker sequences, and the hybridization/selection process is repeated for a second round. After two rounds of direct cDNA selection, the cDNA fragments are cloned, and a library of these direct selected fragments is created.

[0109] The cDNA clones isolated by direct selection are analyzed by two methods. Since a pool of BACs from the disorder region is used to provide the genomic target DNA sequence, the cDNAs must be mapped to BAC genomic clones to verify their chromosomal location. This is accomplished by arraying the cDNAs in microtiter dishes, and replicating their DNA in high density grids. Individual genomic clones known to map to the region are then hybridized to the grid to identify direct selected cDNAs mapping to that region. cDNA clones that are confirmed to correspond to individual BACs are sequenced. To determine whether the cDNA clones isolated by direct selection share sequence identity or similarity to previously identified genes, the DNA and protein coding sequences are compared to publicly available databases using the BLAST family of programs.

[0110] The combination of genomic DNA sequence and cDNA sequence provided by BAC sequencing and by direct cDNA selection yields an initial list of putative genes in the region. The genes in the region were all candidates for the asthma locus. To further characterize each gene, Northern blots were performed to determine the size of the transcript corresponding to each gene, and to determine which putative exons were transcribed together to make an individual gene. For Northern blot analysis of each gene, probes were prepared from direct selected cDNA clones or by PCR amplifying specific fragments from genomic DNA, cDNA or from the BAC encoding the putative gene of interest. The Northern blots gave information on the size of the transcript and the tissues in which it was expressed. For transcripts which were not highly expressed, it was sometimes necessary to perform a reverse transcription PCR assay using RNA from the tissues of interest as a template for the reaction.

[0111] Gene identification by computational methods and by direct cDNA selection provides unique information about the genes in a region of a chromosome. When genes are identified, then it is possible to examine different individuals for mutations in each gene. Variants in gene sequences between individuals can be inherited allelic differences or can arise from mutations in the individuals. Gene sequence variants are clinically important in that they can affect drug action on such gene. Most drugs elicit a safe response in only a fraction of individuals, and drugs are commonly administered to patients with no certainty that they will be safe and effective. Many important drugs are effective in only 30-40% of patients for whom the drug is prescribed, and virtually all drugs cause adverse events in some individuals. Identification of mutations in disorder genes in different individuals will enable a correlation between the safety and efficacy of drug therapies used to treat lung diseases and the genotypes of the treated individuals. This correlation enables health care providers to prescribe a drug regimen which is most appropriate for the individual patient rather than trying different drug regimens in turn until a successful drug is identified. Identification of variants in disorder genes will also have a benefit during the development of new drugs for the treatment of lung diseases, as the ability to correlate genetic variation with the efficacy of new candidate drugs will enhance lead optimization and increase the efficiency and success rate of new drug approvals.

[0112] A. Family Collection

[0113] A critical component of any disease gene search is the careful selection and phenotyping of family resources. The family collection utilized in this study consists of 421 Caucasian affected sibling (“sib”) pairs families collected in the United States and the United Kingdom, as well as an additional 39 Caucasian families from the United Kingdom collected under different ascertainment criteria.

[0114] The affected sibling (or “sib”) pair families in the United States collection were Caucasian families with two affected siblings that were identified through both private practice and community physicians. Advertising was also used to identify candidates. A total of 98 families were collected in Kansas, Nebraska, and Southern California. In the United Kingdom collection, 323 families were identified through physicians' registers in a region surrounding Southampton and including the Isle of Wight.

[0115] Families were included in the study if they met all of the following criteria: (1) the biological mother and biological father were Caucasian and agreed to participate in the study, (2) at least two biological siblings were alive, each with a current physician diagnosis of asthma, and 5 to 21 years of age, and (3) the two siblings were currently taking asthma medications on a regular basis. This included regular, intermittent use of inhaled or oral bronchodilators and regular use of cromolyn, theophylline, or steroids.

[0116] Families were excluded from the study if they met any one of the following criteria: (1) both parents were affected (i.e., with a current diagnosis of asthma, having asthma symptoms, or on asthma medications at the time of the study), or (2) any of the siblings to be included in the study was less than 5 years of age, or (3) any asthmatic family member to be included in the study was taking beta-blockers at the time of the study or (4) any family member had congenital or acquired pulmonary disease at birth (e.g. cystic fibrosis) history of serious cardiac disease (myocardial infarction) or any history of serious pulmonary disease (e.g. emphysema) or (5) pregnant.

[0117] An additional 39 families from the United Kingdom were utilized from an earlier collection effort with different ascertainment criteria. These families were recruited either: 1) without reference to asthma and atopy or 2) by having at least one family member or at least two family members affected with asthma. The randomly ascertained samples were identified from general practitioner registers in the Southampton area. For the families with affected members, the probands were recruited from hospital based clinics in Southampton. Seven pedigrees extended beyond a single nuclear family.

[0118] B. Genome Scan

[0119] In order to identify chromosomal regions linked to asthma, the inheritance pattern of alleles from genetic markers spanning the genome was assessed on the collected family resources. As described above, combining these results with the segregation of the asthma phenotype in these families allows the identification of genetic markers that are tightly linked to asthma, thus providing an indication of the location of genes predisposing affected individuals to asthma. The following discussion describes the protocol used to assess the genotypes of the collected population using genetic markers spanning the entire genome.

[0120] Genotypes of PCR amplified simple sequence microsatellite genetic linkage markers were determined using ABI model 377 Automated Sequencers. Microsatellite markers comprising a variation of a human linkage mapping panel as released from the Cooperative Human Linkage Center (CHLC), also known as the Weber lab screening set version 8, were obtained from Research Genetics Inc. (Huntsville, Ala.) in the fluorescent dye-conjugated form (Dubovsky et al., Hum. Mol. Genet. March; 4(3):449-452 (1995)).

[0121] Our variation of the Weber 8 screening set consists of 529 markers with an average spacing of 6.87 cM (autosomes only) and 6.98 cM (all chromosomes). Eighty-nine percent of the markers consist of either tri- or tetra-nucleotide microsatellites. In addition, there exist no gaps in chromosomal coverage greater than 17.5 cM.

[0122] Study subject genomic DNA (5 μl; 4.5 ng/μl) was amplified in a 10 μl PCR reaction using AmpliTaq Gold DNA polymerase (0.225 U) and containing the final reaction components: 1×PCR buffer (80 mM (NH₄)₂SO₄, 30 mM Tris-HCl (pH 8.8), 0.5% Tween-20), 200 μM each dATP, dCTP, dGTP and dTTP, 1.5-3.5 μM MgCl₂ and 250 μM forward and reverse PCR primers. PCR reactions were set up in 192 well plates (Costar) using a Tecan Genesis 150 robotic workstation equipped with a refrigerated deck. PCR reactions were overlaid with 20 μl mineral oil, and thermocycled on an MJ Research Tetrad DNA Engine equipped with four 192 well heads under the following conditions: 92° C. for 3 min, 6 cycles of 92° C. 30 sec, 56° C. 1 min, 72° C. 45 sec, followed by 20 cycles of 92° C. 30 sec, 55° C. 1 min, 72° C. 45 sec and a 6 min incubation at 72° C. PCR products of 8-12 microsatellite markers were subsequently pooled using a Tecan Genesis 200 robotic workstation into two 96 well microtitre plates (2.0 μl PCR product from TET and FAM labeled markers, 3.01 HEX labeled markers) and brought to a final volume of 25 μl with H₂O. 1.9 μl of pooled PCR product was transferred to a loading plate and combined with 3.0 μl loading buffer (loading buffer is 2.5 l formamide/blue dextran (9.0 mg/ml), 0.5 μl GS-500 TAMRA labeled size standard, Perkin-Elmer/ABI division). Samples were denatured in the loading plate for 4 min at 95° C., placed on ice for 2 min, and electrophoresed in a 5% denaturing polyacrylamide gel (FMC on the ABI 377XL). Samples (0.8 μl) were loaded using an 8 channel Hamilton Syringe pipettor.

[0123] Each gel consisted of 62 study subjects and 2 control subjects (CEPH parents ID #1331-01 and 1331-02, Coriell Cell Repository, Camden, N.J.). Genotyping gels were scored in duplicate by investigators blind to patient identity and affection status using GENOTYPER analysis software V 1.1.12 (ABI Division, Perkin Elmer Corporation). Nuclear families were loaded onto the gel with the parents flanking the siblings to facilitate error detection. Data with allele peak amplitude less than 100, as detected by GENESCAN analysis software V 2.0.2 (ABI Division, Perkin Elmer Corporation), were either left unscored or rerun.

[0124] The final tables obtained from the Genotyper output for each gel analysed were imported into a Sybase Database. Allele calling (binning) was performed using the SYBASE version of the ABAS software (Ghosh et al, Genome Research 7:165-178 (1997)). Offsize bins were checked manually and incorrect calls were corrected or blanked. The binned alleles were then imported into the program MENDEL (Lange et al., Genetic Epidemiology, 5, 471(1988)) for inheritance checking using the USERM13 subroutine (Boehnke et al, AM. J. Hum. Genet. 48:22-25 (1991)). Non-inheritance was investigated by examining the genotyping traces and once all discrepancies were resolved, the subroutine USERM13 was used to estimate allele frequencies.

[0125] C. Linkage Analysis

[0126] Linkage analysis is possible because of the nature of inheritance of chromosomes from parents to offspring. During meiosis, the two parental homologs pair to guide their proper separation to daughter cells. While they are lined up and paired, the two homologs exchange pieces of the chromosomes, in an event called “crossing over” or “recombination.” The resulting chromosomes contain parts that originate from both parental homologs. The closer together two sequences are on the chromosome, the less likely that a recombination event will occur between them, and the more closely linked they are. Data obtained from the different families are combined and analyzed together by a computer using statistical methods. The result is information indicating the evidence for linkage between the genetic markers used and a disease susceptibility locus. A recombination frequency of 1% is equivalent to approximately 1 map unit, a relationship that holds up to frequencies of about 20% or 20 cM. Furthermore, 1 centiMorgan (cM) is roughly equivalent to 1,000 kb of DNA.

[0127] The entire human genome is 3,300 cM long. In order to find an unknown disease gene within 5-10 cM of a marker locus, the whole human genome can be searched with roughly 330 informative marker loci spaced at approximately 10 cM intervals (Botstein et al, Am. J. Hum. Genet., 32:314-331 (1980)). The reliability of linkage results is established by using a number of statistical methods. The methods most commonly used for the detection by linkage analysis of oligogenes involved in the etiology of a complex trait are non-parametric or model-free methods which have been implemented into the computer programs MAPMAKER/SIBS (Kruglyak L & Lander E S, Am J Hum Genet 57:439-454, 1995) and GENEHUNTER (Kruglyak L et al., Am J Hum Genet 58:1347-1363, 1996). Linkage analysis is performed by typing members of families with multiple affected individuals at a given marker locus and evaluating if the affected members (excluding parent-offspring pairs) share alleles at the marker locus that are identical by descent (IBD) more often than expected by chance alone. As a result of the rapid advances in mapping the human genome over the last few years, and concomitant improvements in computer methodology, it has become feasible to carry out linkage analyses using multi-point data. Multi-point analysis provides a simultaneous analysis of linkage between the trait and several linked genetic markers, when the recombination distance among the markers is known. A LOD score statistic is computed at multiple locations along a chromosome to measure the evidence that a susceptibility locus is located nearby. A LOD score is the logarithm base 10 of the ratio of the likelihood that a susceptibility locus exists at a given location to the likelihood that no susceptibility locus is located there. By convention, when testing a single marker, a total LOD score greater than +3.0 (that is, odds of linkage being 1,000 times greater than odds of no linkage) is considered to be significant evidence for linkage.

[0128] Multi-point analysis is advantageous for two reasons. First, the informativeness of the pedigrees is usually increased. Each pedigree has a certain amount of potential information, dependent on the number of parents heterozygous for the marker loci and the number of affected individuals in the family. However, few markers are sufficiently polymorphic as to be informative in all those individuals. If multiple markers are considered simultaneously, then the probability of an individual being heterozygous for at least one of the markers is greatly increased. Second, an indication of the position of the disease gene among the markers may be determined. This allows identification of flanking markers, and thus eventually allows identification of a small region in which the disease gene resides.

[0129] For the initial linkage analysis, the phenotype and asthma affection status were defined by a patient described above who answered the following questions in the affirmative: (i) have you ever had asthma, (ii) do you have a current physician's diagnosis of asthma, and (iii) are you currently taking asthma medications? Medications include inhaled or oral bronchodilators, cromolyn, theophylline or steroids.

[0130] The distribution of the number of genotyped affected siblings was as follows: 88.7% of the families had 2 siblings, 10.8% had 3 siblings and 0.4% had 4 siblings. Ninety six families were ascertained in the US and 345 in the UK.

[0131] Allele sharing methods, implemented in the MAPMAKER/SIBS (Kruglyak L & Lander E S, Am J Hum Genet 57:439-454, 1995), were used on our sample of 462 nuclear with affected sibling pairs. Multipoint linkage analyses were performed using 23 polymorphic markers spanning a 95 cM region on both arms of chromosome 20. The map location and distances between markers were obtained from the genetic maps published by the Marshfield medical research foundation (http://www.marshmed.org/genetics/). Ambiguous order in the Marshfield map was resolved using the program MULTIMAP (Matise T C et al., Nature Genet 6:384-390, 1994).

[0132]FIG. 1 displays the multipoint LOD score against the map location of the markers along the chromosome 20. A Maximum LOD Score (MLS) of 2.9 was obtained at location 7.9 cM, 0.3 cM proximal to marker D20S906. A second MLS of 2.9 was obtained at marker D20S482 at location 12.1 cM. An excess sharing by descent (Identity By Descent, IBD=2) of 0.31 was observed at both maximum LOD scores. Table 1 lists the single and multipoint LOD scores at each marker.

[0133] D. Physical Mapping

[0134] The linkage results for chromosome 20 described above were used to delineate a candidate region for a disorder-associated gene located on chromosome 20. Gene discovery efforts were thus initiated in a 25 cM interval from the 20p telomere (marker D20S502) to marker D20S851, representing a >98% confidence interval. All genes known to map to this interval were pursued as candidates. Intensive physical mapping (BAC contig construction) focused on a 90% confidence interval between markers D20S103 and D20S916, a 15 cM interval. The discovery of novel genes using direct cDNA selection focused on a 95% confidence interval between markers D20S502 (20p telomere) and D20S916, a 17 cM region.

[0135] The following section describes details of the efforts to generate cloned coverage of the disorder gene region on chromosomes 20, i.e., construction of a BAC contig spanning the region. There are two primary reasons for this: 1) to provide genomic clones for DNA sequencing; analysis of this sequence provides information about the gene content of the region, and 2) to provide reagents for direct cDNA selection; this provides additional information about novel genes mapping to the interval. The physical map consists of an ordered set of molecular landmarks, and a set of bacterial artificial chromosome (BAC, Kim, U.-J., et al., (1996), Genomics 34, 213-218 and Shizuya, H., et al., (1992). Proc. Natl. Acad. Sci. USA 89, 8794-8797) clones that contain the disorder gene region from chromosome 20p13-p12.

[0136]FIG. 2 depicts the BAC/STS content contig map in 20p13-p12. Markers used to screen the RPCI-11 BAC library (P. deJong-Roswell Park Cancer Institute) are shown in the top row. For markers that are present in GDB the same nomenclature has been used. BAC clones are shown below the markers as horizontal lines. In particular BAC 1098L22 is labeled. The location of the Gene 216 described herein is indicated at the top of the figure.

[0137] 1. Map Integration. Various publicly available mapping resources were utilized to identify existing STS markers (Olson et al, (1989), Science, 245:1434-1435) in the 20p13-p12 region. Resources included the Genome Database (GDB, http://gdbwww.gdb.org/), Genethon (http://www.genethon.fr/genethon_en.html), Marshfield Center for Medical Genetics (http://www.marshmed.org/genetics/), the Whitehead Institute Genome Center (http://www-genome.wi.mit.edu/), GeneMap98, dbSTS and dbEST (NCBI, http://www.ncbi.nlm.nih.gov/), the Sanger Centre (http://www.sanger.ac.uk/), and the Stanford Human Genome Center (http://www.shgc.stanford.edu/). Maps were integrated manually to identify markers mapping to the disorder region. A list of the markers is provided in Table 1.

[0138] 2. Marker Development. Sequences for existing STSs were obtained from the GDB, RHDB (http://www.ebi.ac.uk/RHdb/), or NCBI and were used to pick primer pairs (overgos, See Table 2) for BAC library screening. Novel markers were developed either from publicly available genomic sequences, proprietary cDNA sequences or from sequences derived from BAC insert ends (described below). Primers were chosen using a script that automatically performs vector and repetitive sequence masking using Crossmatch (P. Green, U. of Washington); subsequent primer picking was performed using a customized Filemaker Pro database. Primers for use in PCR-based clone confirmation or radiation hybrid mapping (described below) were chosen using the program Primer3 (Steve Rozen, Helen J. Skaletsky (1996, 1997); Primer3 is available at http://www-genome.wi.mit.edu/genome_software/other/primer3.html).

[0139] 3. Radiation Hybrid (RH) Mapping. Radiation hybrid mapping was performed against the Genebridge4 panel (Gyapay, et al., (1996), Hum. Mol. Genet. 5:339-46) purchased from Research Genetics, in order to refine the chromosomal localization of genetic markers used in genotyping as well as to identify, confirm and refine localizations of markers from proprietary sequences. Standard PCR procedures were used for typing the RH panel with markers of interest. Briefly, 10 μl PCR reactions contained 25 ng DNA of each of the 93 Genebridge4 RH samples. PCR products were electrophoresed in 2% agarose gels (Sigma) containing 0.5 μg/ml ethidium bromide in 1×TBE at 150 volts for 45 min. The electrophoresis units used were the Model A3-1 systems from Owl Scientific Products. Typically, gels contained 10 tiers of lanes with 50 wells/tier. Molecular weight markers (100 bp ladder, GIBCO/BRL) were loaded at both ends of the gel. Images of the gels were captured with a Kodak DC40 CCD camera and processed with Kodak 1D software. The gel data were exported as tab delimited text files; names of the files included information about the panel screened, the gel image files and the marker screened. These data were automatically imported using a customized Perl script into Filemaker databases for data storage and analysis. The data were then automatically formatted and submitted to an internal server for linkage analysis to create a radiation hybrid map using RHMAPPER (Stein, L., Kruglyak, L., Slonim, D., and El Lander (1995); available from the Whitehead Institute/MIT Center for Genome Research, at http://www.genome.wi.mit.edu/ftp/pub/software/rhmapper/, and via anonymous ftp to ftp.genome.wi.mit.edu, in the directory /pub/software/rhmapper.)

[0140] 4. BAC Library Screening. The protocol used for BAC library screening was based on the “overgo” method, originally developed by John McPherson at Washington University in St. Louis (http://www.tree.caltech.edu/protocols/overgo.html, and Cai, W-W., et al., (1998), Genomics 54:387-397). This method involves filling in the overhangs generated after annealing two primers, each 22 nucleotides in length, that overlap by 8 nucleotides. The resulting labeled 36 bp product is then used in hybridization-based screening of high density grids derived from the RPCI-11 BAC library (Pieter deJong, Roswell Park Cancer Institute, http://bacpac.med.buffalo.edu). Typically, 15 probes were pooled together in one hybridization of 12 filters (13.5 genome equivalents).

[0141] Stock solutions (2 μM) of combined complementary oligos were heated at 80° C. for 5 min. then placed at 37° C. for 10 min followed by storage on ice. Labeling reactions were set up as follows: 1.0 μl H₂O, 5 μl mixed oligo—2 μM each, 0.5 μl BSA (2 mg/ml), 2 μl OLB(-A, -C, -N6) Solution (see below), 0.5 μl ³²P-dATP (3000 Ci/mmol), 0.5 μl ³²P-dCTP (3000 Ci/mmol), 0.5 μl Klenow fragment (5U/μl). The reaction was incubated at room temperature for 1 hr followed by removal of unincorporated nucleotides with Sephadex G50 spin columns.

[0142] OLB(-A, -C, -N6) Solution

[0143] Solution O—1.25 M Tris-HCL, pH 8, 125 M MgCl₂

[0144] Solution A—1 ml Solution O, 18 μl 2-mercaptoethanol, 5 μl 0.1M dTTP, 5 μl 0.1M dGTP

[0145] Solution B—2M HEPES-NaOH, pH 6.6

[0146] Solution C—3 mM Tris-HCl, pH 7.4, 0.2 mM EDTA

[0147] Solutions A, B, and C were combined to a final ratio of 1:2.5:1.5, aliquots were stored at −20° C.

[0148] High density BAC library membranes were pre-wetted in 2×SSC at 58° C. Filters were then drained slightly and placed in hybridization solution (1% Bovine serum albumin, 1 mM EDTA-pH 8.0, 7% SDS, and 0.5 M sodium phosphate) pre-warmed to 58° C. and incubated at 58° C. for 2-4 hr. Typically, 6 filters were hybridized per container. Ten ml of pre-hybridization solution were removed, combined with the denatured overgo probes, and added back to the filters. Hybridization was performed overnight at 58° C. The hybridization solution was removed and filters were washed once in 2×SSC, 0.1% SDS, followed by a 30 minute wash in the same solution but at 58° C. Filters were then washed in 1.5×SSC, 01.% SDS at 58° C. for 30 min. 0.5×SSC, 0.1% SDS at 58° C. for 30 min and finally in 0.1×SSC, 0.1% SDS at 58° C. for 30 min. Filters were then wrapped in Saran Wrap and exposed to film overnight. To remove bound probe, filters were treated in 0.1×SSC, 0.1% SDS pre-warmed to 95° C. and allowed to return to room temperature. Clone addresses were determined as described by instructions supplied by RPCI.

[0149] Recovery of clonal BAC cultures from the library involved streaking out a sample from the appropriate library well onto LB agar (Maniatis, T., Fritsch, E. F., and J. Sambrook, (1982) Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y.) containing 12.5 μg/ml chloramphenicol (Sigma) and incubating overnight. A single colony and a portion of the initial streak quadrant were inoculated into 400 μl LB plus chloramphenicol in wells of a 96 well plate. Cultures were grown overnight at 37° C. For storage, 100 μl of 80% glycerol was added and the plates placed at −80° C. To determine the marker content of clones, aliquots of the 96 well plate cultures were transferred to the surface of nylon filters (GeneScreen Plus, NEN) placed on LB/chloramphenicol Petri plates. Colonies were grown overnight at 37° C. and colony lysis was performed as follows: Filters were placed on pools of 10% SDS for 3 min, 0.5 N NaOH, 1.5 M NaCl for 5 min, and 0.5 M Tris-HCl, pH 7.5, 1 M NaCl for 5 min. Filters were then air dried and washed free of debris in 2×SSC for 1 hr. The filters were air dried for at least 1 hr and DNA crosslinked linked to the membrane using standard conditions. Probe hybridization and filter washing were performed as described above for the primary library screening. Confirmed clones were stored in LB containing 15% glycerol.

[0150] In some cases polymerase chain reaction (PCR) was used to confirm the marker content of clones. PCR conditions for each primer pair were initially optimized with respect to MgCl₂ concentration. The standard buffer was 10 mM Tris-HCl (pH 8.3), 50 mM KCl, MgCl₂, 0.2 mM each dNTP, 0.2 μM each primer, 2.7 ng/μl human DNA, 0.25 units of AmpliTaq (Perkin Elmer) and MgCl₂ concentrations of 1.0 mM, 1.5 mM, 2.0 mM or 2.4 mM. Cycling conditions included an initial denaturation at 94° C. for 2 minutes followed by 40 cycles at 94° C. for 15 seconds, 55° C. for 25 seconds, and 72° C. for 25 seconds followed by a final extension at 72° C. for 3 minutes. Depending on the results from the initial round of optimization the conditions were further optimized if necessary. Variables included increasing the annealing temperature to 58° C. or 60° C., increasing the cycle number to 42 and the annealing and extension times to 30 seconds, and using AmpliTaqGold (Perkin Elmer).

[0151] 5. BAC DNA Preparation. Several different types of DNA preparation methods were used for isolation of BAC DNA. The manual alkaline lysis miniprep protocol listed below (Maniatis, T., Fritsch, E. F., and J. Sambrook, (1982) Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y.) was successfully used for most applications, i.e., restriction mapping, CHEF gel analysis and FISH mapping, but was not reproducibly successful in endsequencing. The Autogen protocol described below was used specifically for BAC DNA preparation for endsequencing purposes.

[0152] For manual alkaline lysis BAC minipreps, bacteria were grown in 15 ml Terrific Broth containing 12.5 μg/ml chloramphenicol in a 50 ml conical tube at 37° C. for 20 hrs with shaking at 300 rpm. The cultures were centrifuged in a Sorvall RT 6000 D at 3000 rpm (1800×g) at 4° C. for 15 min. The supernatant was then aspirated as completely as possible. In some cases cell pellets were frozen at −20° C. at this step for up to 2 weeks. The pellet was then vortexed to homogenize the cells and minimize clumping. 250 μl of P1 solution (50 mM glucose, 15 mM Tris-HCl, pH 8, 10 mM EDTA, and 100 μg/ml RNase A) was added and the mixture pipeted up and down to mix. The mixture was then transferred to a 2 ml Eppendorf tube. 350 μl of P2 solution (0.2 N NaOH, 1% SDS) was then added, and the mixture mixed gently and incubated for 5 min at room temperature. 350 μl of P3 solution (3M KOAc, pH 5.5) was added and the mixture mixed gently until a white precipitate formed. The solution was incubated on ice for 5 min and then centrifuged at 4° C. in a microfuge for 10 min. The supernatant was transferred carefully (avoiding the white precipitate) to a fresh 2 ml Eppendorf tube, and 0.9 ml of isopropanol was added; the solution was mixed and left on ice for 5 min. The samples were centrifuged for 10 min, and the supernatant removed carefully. Pellets were washed in 70% ethanol and air dried for 5 min. Pellets were resuspended in 200 μl of TE8 (10 mM Tris-HCl, pH 8.0, 1.0 mM EDTA, pH 8.0), and RNase (Boehringer Mannheim) added to 100 μg/ml. Samples were incubated at 37° C. for 30 min, then precipitated by addition of NH₄OAc to 0.5 M and 2 volumes of ethanol. Samples were centrifuged for 10 min, and the pellets washed with 70% ethanol followed by air drying and dissolving in 50 μl TE8. Typical yields for this DNA prep were 3-5 μg/15 ml bacterial culture. Ten to 15 μl were used for EcoRI restriction analysis; 5 μl was used for NotI digestion and clone insert sizing by CHEF gel electrophoresis.

[0153] Autogen 740 BAC DNA preparations for endsequencing were prepared by dispensing 3 ml of LB media containing 12.5 μg/ml of chloramphenicol into autoclaved Autogen tubes. A single tube was used for each clone. For inoculation, glycerol stocks were removed from −70° C. storage and placed on dry ice. A small portion of the glycerol stock was removed from the original tube with a sterile toothpick and transferred into the Autogen tube; the toothpick was left in the Autogen tube for at least two minutes before discarding. After inoculation the tubes were covered with tape making sure the seal was tight. When all samples were inoculated, the tube units were transferred into an Autogen rack holder and placed into a rotary shaker at 37° C. for 16-17 hours at 250 rpm. Following growth, standard conditions for BAC DNA preparation, as defined by the manufacturer, were used to program the Autogen. Samples were not dissolved in TE8 as part of the program—DNA pellets were left dry. When the program was complete the tubes were removed from the output tray and 30 μl of sterile distilled and deionized H2O was added directly to the bottom of the tube. The tubes were then gently shaken for 2-5 seconds and then covered with parafilm and incubated at room temperature for 1-3 hours. DNA samples were then transferred to an Eppendorf tube and used either directly for sequencing or stored at 4° C. for later use.

[0154] 6. BAC Clone Characterization. DNA samples prepared either by manual alkaline lysis or the Autogen protocol were digested with EcoRI for analysis of restriction fragment sizes. These data were used to compare the extent of overlap among clones. Typically 1-2 μg were used for each reaction. Reaction mixtures included: 1× Buffer 2 (New England Biolabs), 0.1 mg/ml bovine serum albumin (New England Biolabs), 50 μg/ml RNase A (Boehringer Mannheim), and 20 units of EcoRI (New England Biolabs) in a final volume of 25 μl. Digestions were incubated at 37° C. for 4-6 hours. BAC DNA was also digested with NotI for estimation of insert size by CHEF gel analysis (see below). Reaction conditions were identical to those for EcoRI except that 20 units of NotI were used. Six μl of 6× Ficoll loading buffer containing bromphenol blue and xylene cyanol was added prior to electrophoresis.

[0155] EcoRI digests were analyzed on 0.6% agarose (Seakem, FMC Bioproducts) in 1×TBE containing 0.5 μg/ml ethidium bromide. Gels (20 cm×25 cm) were electrophoresed in a Model A4 electrophoresis unit (Owl Scientific) at 50 volts for 20-24 hrs. Molecular weight size markers included undigested lambda DNA, HindIII digested lambda DNA, and HindIII digested X174 DNA. Molecular weight markers were heated at 65° C. for 2 min prior to loading the gel. Images were captured with a Kodak DC40 CCD camera and analyzed with Kodak 1D software.

[0156] NotI digests were analyzed on a CHEF DRII (BioRad) electrophoresis unit according to the manufacturer's recommendations. Briefly, 1% agarose gels (BioRad pulsed field grade) were prepared in 0.5×TBE, equilibrated for 30 min in the electrophoresis unit at 14° C., and electrophoresed at 6 volts/cm for 14 hrs with circulation. Switching times were ramped from 10 sec to 20 sec. Gels were stained after electrophoresis in 0.5 μg/ml ethidium bromide. Molecular weight markers included undigested lambda DNA, HindIII digested lambda DNA, lambda ladder PFG ladder, and low range PFG marker (all from New England Biolabs).

[0157] 7. BAC Endsequencing. The sequence of BAC insert ends utilized DNA prepared by either of the two methods described above. The ends of BAC clones were sequenced for the purpose of filling gaps in the physical map and for gene discovery information. The following vector primers specific to the BAC vector pBACe3.6 were used to generate endsequence from BAC clones: pBAC 5′-2 TGT AGG ACT ATA TTG CTC pBAC 3′-1 CGA CAT TTA GGT GAC ACT

[0158] The following sequencing protocol using ABI dye-terminator chemistry was used to set up sequencing reactions for 96 clones. The BigDye (Mix: Perkin Elmer/ABI BigDye) Terminator Ready Reaction Mix with AmpliTaq” FS, Part number 4303151, was used for sequencing with fluorescently labelled dideoxy nucleotides. A master sequencing mix was prepared for each primer reaction set including:

[0159] 1600 μl of BigDye terminator mix (ABI)

[0160] 800 μl of 5×CSA buffer (ABI)

[0161] 800 μl of primer (either pBAC 5′-2 or pBAC 3′-1 at 3.2 μM)

[0162] The sequencing cocktail was vortexed to ensure it was well-mixed and 32 μl was aliquoted into each PCR tube. Eight μl of the Autogen DNA for each clone was transferred from the DNA source plate to a corresponding well of the PCR plate. The PCR plates were sealed tightly and centrifuged briefly to collect all the reagents. Cycling conditions were as follows:

[0163] 95° C. for 5 minutes

[0164] 95° C. for 30 seconds

[0165] 50° C. for 20 seconds

[0166] 65° C. for 4 minutes

[0167] Go to steps 2 through 4 above for an additional 74 times

[0168] 4° C. forever

[0169] At the end of the sequencing reaction, the plates were removed from the thermocycler and centrifuged briefly. Centri•Sep 96 plates were then used according to manufacturer's recommendation to remove unincorporated nucleotides, salts and excess primers. Each sample was resuspended in 1.5 μl of loading dye of which 1.3 μl was loaded on ABI 377 Fluorescent Sequencers. The resulting endsequences were then used to develop markers to rescreen the BAC library for filling gaps and were also analyzed by BLAST searching for EST or gene content.

[0170] E. Sub-Cloning and Sequencing of BAC RPCI_(—)1098L22 from 20p13-p12

[0171] The physical map of the chromosome 20 region provides the location of the BAC RPCI_(—)1098L22 clone that contains Gene 216 (see FIG. 2). DNA sequencing of BAC, RPCI 11-1098L22 from the region has been completed. BAC RPCI 11-1098L22 DNA, (the “BAC DNA”) was isolated according to one of two protocols: either a Qiagen purification (Qiagen, Inc., Chatsworth, Calif., per manufacturer's instructions) or a manual purification using a method which is a modification of the standard alkaline lysis/Cesium Chloride preparation of plasmid DNA (see e.g., Ausubel et al, (1997), Current Protocols in Molecular Biology, John Wiley & Sons). Briefly, for the manual protocol, cells were pelleted, resuspended in GTE (50 mM glucose, 25 mM Tris-Cl (pH 8), 10 mM EDTA) and lysozyme (50 mg/ml solution), followed by NaOH/SDS (1% SDS/0.2N NaOH) and then an ice-cold solution of 3M KOAc (pH 4.5-4.8). RnaseA was added to the filtered supernatant, followed by treatment with Proteinase K and 20% SDS. The DNA was then precipitated with isopropanol, dried and resuspended in TE (10 mM Tris, 1 mM EDTA (pH 8.0)). The BAC DNA was further purified by Cesium Chloride density gradient centrifugation (Ausubel et al, (1997), Current Protocols in Molecular Biology, John Wiley & Sons).

[0172] Following isolation, the BAC DNA was hydrodynamically sheared using HPLC (Hengen, et al., (1997), Trends in Biochem. Sci., 22:273-274) to an insert size of 2000-3000 bp. After shearing, the DNA was concentrated and separated on a standard 1% agarose gel. A single fraction, corresponding to the approximate size, was excised from the gel and purified by electroelution (Sambrook et al, (1989), Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring, N.Y.).

[0173] The purified DNA fragments were then blunt-ended using T4 DNA polymerase. The healed DNA was then ligated to unique BstXI-linker adapters (5′ GTCTTCACCACGGGG and 5′ GTGGTGAAGAC in 100-1000 fold molar excess). These linkers are complimentary to the BstXI-cut pMPX vectors, while the overhang is not self-complimentary. Therefore, the linkers will not concatemerize nor will the cut-vector re-ligate to itself easily. The linker-adapted inserts were separated from unincorporated linkers on a 1% agarose gel and purified using GeneClean (BIO 101, Inc.). The linker-adapted insert was then ligated to a modified pBlueScript vector to construct a “shotgun” subclone library. The vector contains an out-of-frame lacZ gene at the cloning site which becomes in-frame in the event that an adapter-dimer is cloned, allowing these to be avoided by their blue color.

[0174] All subsequent steps were based on sequencing by ABI377 automated DNA sequencing methods. Only major modifications to the protocols are highlighted. Briefly, the library was then transformed into DH5-competent cells (Gibco/BRL, DH5-transformation protocol). Quality was assessed by plating onto antibiotic plates containing ampicillin and IPTG/Xgal. The plates were incubated overnight at 37° C. Successful transformants were then used for plating of clones and picking for sequencing. The cultures were grown overnight at 37° C. DNA was purified using a silica bead DNA preparation (Ng et al, Nucl. Acids Res., 24:5045-5047 (1996)) method. In this manner, 25 μg of DNA was obtained per clone.

[0175] These purified DNA samples were then sequenced using ABI dye-terminator chemistry. The ABI dye terminator sequence reads were run on ABI377 machines and the data were directly transferred to UNIX machines following lane tracking of the gels. All reads were assembled using PHRAP (P. Green, Abstracts of DOE Human Genome Program Contractor-Grantee Workshop V, January 1996, p.157) with default parameters and quality scores. The assembly was done at 8-fold coverage and yielded 1 contig, BAC RPCI 11-1098L22. SEQ ID NO:7 (FIGS. 20A-20G) comprises a portion of the BAC which includes the genomic sequence of Gene 216.

[0176] F. Gene Identification

[0177] Any gene or EST mapping to the interval based on public map data or proprietary map data was considered a candidate respiratory disease gene. Public map data were derived from several sources: the Genome Database (GDB, http://gdbwww.gdb.org/), the Whitehead Institute Genome Center (http://www-genome.wi.mit.edu/), GeneMap98, UniGene, OMIM, dbSTS and dbEST (NCBI, http://www.ncbi.nlm.nih.gov/), the Sanger Centre (http://www.sanger.ac.uk/), and the Stanford Human Genome Center (http://www-shgc.stanford.edu/). Proprietary data was obtained from sequencing genomic DNA (cloned into BACs) or cDNAs (identified by direct selection, screening of cDNA libraries or full length sequencing of IMAGE Consortium (http://www-bio.11nl.gov/bbrp/image.html) cDNA clones).

[0178] 1. Gene Identification from clustered DNA fragments. DNA sequences corresponding to gene fragments in public databases (Genbank and human dbEST) and proprietary cDNA sequences (IMAGE consortium and direct selected cDNAs) were masked for repetitive sequences and clustered using the PANGEA Systems (Oakland, Calif.) EST clustering tool. The clustered sequences were then subjected to computational analysis to identify regions bearing similarity to known genes. This protocol included the following steps:

[0179] i. The clustered sequences were compared to the publicly available Unigene database (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; vww.ncbi.nlm.nih.gov) using the blastn2 algorithm (Altschul et al, Nucl. Acids Res., 25:3389-3402 (1997)). The parameters for this search were: E=0.05, v=50, B=50 (where E is the expected probability score cutoff, V is the number of database entries returned in the reporting of the results, and B is the number of sequence alignments returned in the reporting of the results (Altschul et al, J. Mol. Biol., 215:403-410 (1990)).

[0180] ii. The clustered sequences were compared to the Genbank database (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov) using blastn2 (Altschul et al, Nucl. Acids. Res., 25:3389-3402 (1997)). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0181] iii. The clustered sequences were translated into protein for all six reading frames, and the protein sequences were compared to a non-redundant protein database compiled from Genpept Swissprot PIR (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0182] iv. The clustered sequences were compared to BAC sequences (see below) using blastn2 (Altschul et al, Nucl. Acids. Res., 25:3389-3402 (1997)). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0183] 2. Gene Identification from BAC Genomic Sequence. Following assembly of the BAC sequences into contigs, the contigs were subjected to computational analyses to identify coding regions and regions bearing DNA sequence similarity to known genes. This protocol included the following steps:

[0184] i. Contigs were degapped. The sequence contigs often contain symbols (denoted by a period symbol) that represent locations where the individual ABI sequence reads have insertions or deletions. Prior to automated computational analysis of the contigs, the periods were removed. The original data were maintained for future reference.

[0185] ii. BAC vector sequences were “masked” within the sequence by using the program crossmatch (Phil Green, http:\\chimera.biotech.washington.edu\UWGC). Since the shotgun library construction detailed above left some BAC vector in the shotgun libraries, this program was used to compare the sequence of the BAC contigs to the BAC vector and to mask any vector sequence prior to subsequent steps. Masked sequence was marked by an “X” in the sequence files, and remained inert during subsequent analyses.

[0186] iii. E. coli sequences contaminating the BAC sequences were masked by comparing the BAC contigs to the entire E. coli DNA sequence.

[0187] iv. Repetitive elements known to be common in the human genome were masked using crossmatch. In this implementation of crossmatch, the BAC sequence is compared to a database of human repetitive elements (Jerzy Jerka, Genetic Information Research Institute, Palo Alto, Calif.). The masked repeats were marked by X and remained inert during subsequent analyses.

[0188] v. The location of exons within the sequence was predicted using the MZEF computer program (Zhang, Proc. Natl. Acad. Sci., 94:565-568 (1997); (Burge and Karlin, J. Mol. Biol., 268:78-94))

[0189] vi. The sequence was compared to the publicly available unigene database (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov) using the blastn2 algorithm (Altschul et al, Nucl. Acids Res., 25:3389-3402 (1997)). The parameters for this search were: E=0.05, v=50, B=50 (where E is the expected probability score cutoff, V is the number of database entries returned in the reporting of the results, and B is the number of sequence alignments returned in the reporting of the results (Altschul et al, J. Mol. Biol., 215:403-410 (1990)).

[0190] vii. The sequence was translated into protein for all six reading frames, and the protein sequences were compared to a non-redundant protein database compiled from Genpept Swissprot PIR (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0191] viii. The BAC DNA sequence was compared to a database of clustered sequences using blastn2 (Altschul et al, Nucl. Acids. Res., 25:3389-3402 (1997)). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above. The database of clustered sequences was prepared utilizing a proprietary clustering technology (Pangea Systems, Inc.) using cDNA clones derived from direct selection experiments (described below), human dbEST mapping to the 20p13-p12 region, proprietary cDNAs, Genbank genes and IMAGE consortium cDNA clones.

[0192] ix. The BAC sequence was compared to the sequences derived from the ends of BACs from the region on chromosomes 20 using blastn2 (Altschul et al, Nucl. Acids. Res., 25:3389-3402 (1997)). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0193] x. The BAC sequence was compared to the Genbank database (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov) using blastn2 (Altschul et al, Nucl. Acids. Res., 25:3389-3402 (1997)). The parameters for this search were E=0.05, V=50, B=50; where E, V, and B are defined as above.

[0194] xi. The BAC sequence was compared to the STS division of Genbank database (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov) using blastn2 (Altschul et al., 1997). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0195] xii. The BAC sequence was compared to the Expressed Sequence Tag (EST) Genbank database (National Center for Biotechnology Information, National Library of Medicine, 38A, 8N905, 8600 Rockville Pike, Bethesda, Md. 20894; www.ncbi.nlm.nih.gov) using blastn2 (Altschul et al., Nucl. Acids. Res., 25:3389-3402 (1997)). The parameters for this search were E=0.05, V=50, B=50, where E, V, and B are defined as above.

[0196] 3. Gene Identification in region 20p13-p12 by Direct cDNA Selection.

[0197] Direct cDNA selection is a powerful technique for the identification of genes mapping to a particular genomic interval. It involves hybridizing genomic DNA (in this case, BACs) from a region of interest to pools of cDNAs derived from various tissue sources. The procedure permits the rapid isolation of cDNAs without the need for tedious cDNA library screening approaches. The tissues used in this study included unstimulated Th2 cells, Th2 cells stimulated with TPA, bronchial smooth muscle cells, unstimulated Th0 cells, Th0 stimulated with anti CD3 and TPA, pulmonary artery endothelium cells, Lung microvascular endothelial cells, bronchial epithelium cells, normal and asthmatic lung, small airway epithelium cells and lung fibroblasts. These cell types are implicated in the pathophysiology of asthma and are expected to express genes involved in the asthmatic inflammatory response. In addition, RNA isolated from brain was used because it is generally thought that brain expresses a diverse array of genes.

[0198] Cytoplasmic RNA was isolated as described by Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratories, Cold Spring Harbor, N.Y., (1989). Approximately 400-600 μg of cytoplasmic RNA was isolated from 50 million cells.

[0199] Total RNA was isolated from normal and asthmatic lung tissue using TRIzol Reagents (Gibco BRL, Rockville, Md.) which are ready-to-use monophasic solutions of guanadinium isothiocyanate and phenol (Chomczynski, P. and Sacchi, N. (1987) Anal. Biochem., 162:156-159; Chomczynski, P., Bowers-Finn, R., and Sabatini, L. (1987) J. NIH Res. 6:83; Simms, D., Cizdiel, P. E., and Chomczynski, P. (1993) Focus 15:99; Chomczynski, P. (1993) BioTechniques 15:532). Five hundred milligrams of frozen tissue was crushed into a fine powder using a Bessman tissue pulverizer (Fisher Scientific). The TRIzol Reagents were mixed with the crushed tissue according to the manufacturer's recommendations to isolate total RNA.

[0200] To ascertain whether there was genomic DNA or heteronuclear RNA contamination within the RNA isolates, PCR and RT/PCR were performed, respectively. The PCR analysis was performed using primers (Research Genetics) that amplify STS markers from chromosomes 2 (D2S2358), 7 (D7S2776, D7S685), 10 (D10S228, D10S1755) and 20 (D20S905, D20S95). All PCR reactions were performed in a volume of 25 μl that contained 1 μl of RNA, 10 mM Tris-HCl (pH 8.3), 50 mM KCl, 1.5 mM MgCl2, 0.001% gelatin, 200 mM each dNTPs, 10 μM of each primer and 1 unit Taq DNA polymerase (Perkin Elmer). A Perkin Elmer 9600 was used to amplify the material under the following conditions: 30 seconds at 94° C., 30 seconds at 55° C. and 30 seconds at 72° C. for 30 cycles. The RT/PCR analysis was performed using the SuperScript One-Step RT-PCR System (Gibco-BRL, Rockville, Md.) according to the manufacturer's recommendations. All PCR and RT/PCR products were evaluated by electrophoresis on a 1% agarose gel.

[0201] Poly A+ RNA was prepared from the total RNA isolated from the human primary cells and lung tissues using Dynabeads Oligo(dT) according to the manufacturer's recommendations (Dynal, Lake Success, N.Y.). Approximately 4 μg of messenger RNA was isolated from 150 μg of total RNA for each cell type and tissue source. Total RNA isolated from brain tissue was purchased from Clontech (Palo Alto, Calif.) and poly A+ RNA was prepared from this material using the Dynabeads Oligo(dT) as described above.

[0202] Oligo dT and random primed cDNA pools were generated from the mRNA isolated from each cell type and tissue source. Briefly, 2.0 μg mRNA was mixed with oligo(dT) primer in one reaction, and 2.0 μg mRNA was mixed with random hexamers in another reaction, and converted to double stranded complementary DNA using the SuperScript Choice System for cDNA Synthesis (Gibco-BRL, Rockville, Md.) according to manufacturer's recommendations.

[0203] Four different paired phosphorylated cDNA linkers (Table 3) were annealed by mixing in a 1:1 ratio (10 μg each), incubating at 65° C. for 5 minutes and allowing to cool to room temperature for 30 minutes. The annealed linkers were ligated to the oligo(dT) and random primed cDNA pools from various tissue and cell sources (Table 3) according to manufacturer's instructions (Gibco-BRL, Rockville, Md.). The linker sequence provides a tag to identify which tissue from which that particular RNA was derived after sequencing the cDNAs.

[0204] The cDNA pools were evaluated for length distribution by PCR amplification using 1 μl of a 1:1, 1:10, and 1:100 dilution of the ligation reaction. All PCR reactions were performed in a volume of 25 μl which contained 1 μl of DNA, 10 mM Tris-HCl (pH 8.3), 50 mM KCl, 1.5 mM MgCl2, 0.001% gelatin, 200 mM each dNTPs, 10 μM of each primer and 1 unit Taq DNA polymerase (Perkin Elmer). A Perkin Elmer 9600 was used to amplify the material under the following conditions: 30 seconds at 94° C., 30 seconds at 55° C. and 2 minutes at 72° C. for 30 cycles. The length distribution of the amplified cDNA pools was evaluated by electrophoresis on a 1% agarose gel. The PCR reaction that gave the best representation of the random primed and oligo dT primed cDNA pools was scaled up so that ˜2-3 μg of each cDNA pool was produced and this represented a 1×PCR reaction of the starting cDNA pools.

[0205] One microgram of BAC RPCI 1098L22 DNA that spanned Gene 216 was pooled in equimolar amounts and 1 μg of the isolated genomic DNA was labelled with biotin 16-UTP by nick translation in accordance with the manufacturer's instructions (Boehringer Mannheim). The incorporation of the biotin was monitored by standard methods (Del Mastro and Lovett, Methods in Molecular Biology, Humana Press Inc., NJ (1996)

[0206] a. Direct cDNA Selection for Region 20p13-p12.

[0207] Direct cDNA selection was performed using standard methods (Del Mastro and Lovett, Methods in Molecular Biology, Humana Press Inc., NJ (1996)). Briefly, 1 μg of each cDNA pool was placed into individual PCR tubes. A total of 30 direct selection experiments were arrayed into a PCR plate. Suppression of high copy repeats, ribosomal RNA and plasmid in the cDNA pools was performed to a Cot of 20. One hundred nanograms of biotinylated BAC DNA was mixed with the suppressed cDNAs and hybridized in solution to a Cot of 20. The biotinylated DNA and the cognate cDNAs were then captured on streptavidin-coated paramagnetic beads. The beads were washed and the primary selected cDNAs were eluted. The products from the first round of direct selection were PCR amplified using appropriate primers (shown in Table 3) and a second round of direct selection was then performed.

[0208] b. Cloning and Arraying of the Secondary Selected Material.

[0209] The random primed product of the second round of direct selection (the secondary selected material) from lung microvascular endothelial cells, Th0/unstimulated cells, lung fibroblast cells, Th2/unstimulated cells, pulmonary artery endothelium cells, normal lung, small airway epithelium cells, bronchial epithelium cells and Th0 cells stimulated with TPA, and oligo dT primed Th0 cells stimulated with TPA was PCR amplified with modified primers that were used during the two rounds of direct cDNA selection (See Table 4 below).

[0210] The amplified material was cloned into the UDG vector pAMP10 (Gibco-BRL, Rockville, Md.) in accordance with the manufacturer's recommendations. Four hundred and eighty clones were picked from each transformed source and arrayed into five 96 well microtiter plate. Each selected cDNA library was stamped, in duplicate, in a high density format onto Hybond N+ nylon membrane (Amersham). The bacteria were grown overnight at 37° C., and the membranes were processed as recommended by the manufacturer.

[0211] To identify which of the clones represented the most common contaminants, such as high copy repeats and ribosomal RNA, a radiolabelled probe containing 1 μg of Cot1 DNA and 0.5 μg ribosomal DNA was hybridized at 65° C. to the high density filters (Sambrook et al, (1989) Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratories, Cold Spring Harbor, N.Y.). The filters were washed three times in buffer (0.1×SSC, 0.1% SDS) at 65° C. and were autoradiographed. Those cDNAs that showed duplicate signals were scored as background contaminants. The remainder of the clones were re-arrayed into 96 well microtiter plates. A total of one hundred and eleven 96 well microtiter plates containing 10638 secondary selected clones were sequenced: Three 96 well microtiter plates from all the random primed selections, except Th0 cells stimulated with TPA where only two plates were sequenced, and one 96 well microtiter plate from Th0 cells stimulated with TPA oligo dT selection. All cDNA clones were sequenced using M13 dye primer terminator cycle sequencing kits (Applied Biosystems), and the data collected by the ABI 377 automated fluorescence sequencer (Applied Biosystems).

[0212] Further background clones such as high copy repeats, ribosomal RNA, plasmid, mitochondrial, E. coli and yeast that were not identified in the hybridization process were removed from the dataset using in silico methods. This process yielded 787 cDNA clones for further analysis. These clones were clustered using Pangea System's EST Clustering Tool (Oakland, Calif.) and analyzed with BLASTN, X and FASTA programs. This software tool enables one to construct full length gene sequences by aligning the DNA fragments.

[0213] These direct selected clones were combined with the proprietary cDNA sequences, and sequences within the public domain (dbEST and Genbank) then clustered using the Pangea Systems EST Clustering Tool. These clustered sequences are known to those skilled in the art as consensus sequences assisted in extending the gene sequences disclosed herein.

[0214] c. Mapping Analysis.

[0215] Those BACs that were identified, and mapped to the region 20p13-p12 were used to determine which cDNA clones map back using standard hybridization methods as described by Sambrook et al, (1989) Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratories, Cold Spring Harbor, N.Y. The DNA from each BAC was isolated using Nucleobond AX columns as described by the manufacturer (Clontech, Palo Alto, Calif.) and hybridized at 65° C. to high density filters containing the sequenced cDNAs. Those cDNAs that showed duplicate signals were scored as mapping back to the genomic clone and to the region. These cDNAs were studied further as disorder associated gene(s).

[0216] Through mapping analysis, BAC RPCI 1098L22 was identified as containing Gene 216. This BAC sequence (SEQ ID NO:7, FIGS. 20A-20G) is genomic nucleotide sequence corresponding to the cDNA sequence of Gene 216 (SEQ ID NO:1-SEQ ID NO:3).

[0217] G. cDNA Cloning and Expression Analysis

[0218] 1. Construction of cDNA libraries. Directionally cloned cDNA libraries from normal lung and bronchial epithelium were constructed using standard methods described previously (Soares et. al., 1994, Automated DNA Sequencing and Analysis, Adams, Fields and Venter, Eds., Academic Press, NY, pages 110-114). Total and cytoplasmic RNAs were extracted from tissue or cells by homogenizing the sample in the presence of Guanidinium Thiocyanate-Phenol-Chloroform extraction buffer (e.g. Chomczynski and Sacchi, Anal. Biochem., 162:156-159 (1987)) using a polytron homogenizer (Brinkman Instruments). PolyA+ RNA was isolated from total/cytoplasmic RNA using dynabeads-dT according to the manufacturer's recommendations (Dynal, Inc.). The ds cDNA synthesized was then ligated into the plasmid vector pBluescript II KS+ (Stratagene, La Jolla, Calif.), and the ligation mixture was transformed into E. coli host DH10B or DH12S by electroporation (Soares, 1994). Following overnight growth at 37° C., DNA was recovered from the E. coli colonies after scraping the plates by processing as directed for the Mega-prep kit (Qiagen, Chatsworth, Calif.). The quality of the cDNA libraries was estimated by counting a portion of the total number of primary transformants, determining the average insert size and the percentage of plasmids with no cDNA insert. Additional cDNA libraries (human total brain, heart, kidney, leukocyte, and fetal brain) were purchased from Life Technologies, Bethesda, Md.

[0219] cDNA libraries, both oligo (dT) and random hexamer-primed were used for isolating cDNA clones mapping within the disorder critical region. Four 10×10 arrays of each of the cDNA libraries were prepared as follows: the cDNA libraries were titered to 2.5×10⁶ using primary transformants. The appropriate volume of frozen stock was used to inoculate 2 L of LB/ampicillin (100 μg/μl). 400 aliquots containing 4 ml of the inoculated liquid culture were generated. Each tube contained about 5000 cfu. The tubes were incubated at 30° C. overnight with shaking until an OD of 0.7-0.9 was obtained. Frozen stocks were prepared for each of the cultures by aliquotting 300 μl of culture and 100 μl of 80% glycerol. Stocks were frozen in a dry ice/ethanol bath and stored at −70° C. DNA was isolated from the remaining culture using the Qiagen (Chatsworth, Calif.) spin mini-prep it according to the manufacturer's instructions. The DNAs from the 400 cultures were pooled to make 80 column and row pools. Markers were designed to amplify putative exons from candidate genes. Once a standard PCR condition was identified and specific cDNA libraries were determined to contain cDNA clones of interest, the markers were used to screen the arrayed library. Positive addresses indicating the presence of cDNA clones were confirmed by a second PCR using the same markers.

[0220] Once a cDNA library was identified as likely to contain cDNA clones corresponding to a specific transcript of interest from the disorder critical region, it was used to isolate a clone or clones containing cDNA inserts. This was accomplished by a modification of the standard “colony screening” method (Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor N.Y. (1989)). Specifically, twenty 150 mm LB+ampicillin agar plates were spread with 20,000 colony forming units (cfu) of cDNA library and the colonies allowed to grow overnight at 37° C. Colonies were transferred to nylon filters (Hybond from Amersham, or equivalent) and duplicates prepared by pressing two filters together essentially as described (Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor N.Y. (1989)). The “master” plate was then incubated an additional 6-8 hrs to allow the colonies additional growth. The DNA from the bacterial colonies was then bound onto the nylon filters by treating the filters sequentially with denaturing solution (0.5 N NaOH, 1.5 M NaCl) for two minutes, neutralization solution (0.5 M Tris-Cl pH 8.0, 1.5 M NaCl) for two minutes (twice). The bacterial colonies were removed from the filters by washing in a solution of 2×SSC/2% SDS for one minute while rubbing with tissue paper. The filters were air dried and baked under vacuum at 80° C. for 1-2 hrs to cross link the DNA to the filters.

[0221] cDNA hybridization probes were prepared by random hexamer labelling (Fineberg and Vogelstein, Anal. Biochem., 132:6-13 (1983)) or by including gene-specific primers and no random hexamers in the reaction (for small fragments). The colony membranes were then pre-washed in 10 mM Tris-Cl pH 8.0, 1 M NaCl, 1 mM EDTA, 0.1% SDS for 30 minutes at 55° C. Following the pre-wash, the filters were pre-hybridized in >2 ml/filter of 6×SSC, 50% deionized formamide, 2% SDS, 5× Denhardt's solution, and 100 mg/ml denatured salmon sperm DNA, at 42° C. for 30 minutes. The filters were then transferred to hybridization solution (6×SSC, 2% SDS, 5× Denhardt's, 100 mg/ml denatured salmon sperm DNA) containing denatured a-32P-dCTP-labelled cDNA probe and incubated overnight at 42° C.

[0222] The following morning, the filters were washed under constant agitation in 2×SSC, 2% SDS at room temperature for 20 minutes, followed by two washes at 65° C. for 15 minutes each. A second wash was performed in 0.5×SSC, 0.5% SDS for 15 minutes at 65° C. Filters were then wrapped in plastic wrap and exposed to radiographic film. Individual colonies on plates were aligned with the autoradiograph and positive clones picked into a 1 ml solution of LB Broth containing ampicillin. After shaking at 37° C. for 1-2 hours, aliquots of the solution were plated on 150 mm plates for secondary screening. Secondary screening was identical to primary screening (above) except that it was performed on plates containing 250 colonies so that individual colonies could be clearly identified. Positive cDNA clones were characterized by restriction endonuclease cleavage, PCR, and direct sequencing to confirm the sequence identity between the original probe and the isolated clone.

[0223] To obtain the full-length cDNA, novel sequence from the 5′-end of the clone was used to reprobe the library. This process is repeated until the length of the cDNA cloned matched that of the mRNA, estimated by Northern analysis.

[0224] Rapid Amplification of cDNA ends (RACE) was performed following the manufacturer's instructions using a Marathon cDNA Amplification Kit (Clontech, Palo Alto, Calif.) as a method for cloning the 5′ and 3′ ends of candidate genes. cDNA pools were prepared from total RNA by performing first strand synthesis, where a sample of total RNA sample was mixed with a modified oligo (dT) primer, heated to 70° C., cooled on ice and followed by the addition of: 5×first strand buffer, 10 mM dNTP mix, and AMV Reverse Transcriptase (20 U/μl). The reaction mixture was incubated at 42° C. for an hour and placed on ice. For second strand synthesis, the following components were added directly to the reaction tube: 5× second strand buffer, 10 mM DNTP mix, sterile water, 20× second strand enzyme cocktail and the reaction tube was incubated at 16° C. for 1.5 hours. T4 DNA Polymerase was added to the reaction tube and incubated at 16° C. for 45 minutes. The second-strand synthesis was terminated with the addition of an EDTA/Glycogen mix. The sample was subjected to a phenol/chloroform extraction and an ammonium acetate precipitation. The cDNA pools were checked for quality by analyzing on an agarose gel for size distribution. Marathon cDNA adapters were then ligated onto the cDNA ends. The specific adapters contained priming sites that allowed for amplification of either 5′ or 3′ ends, and varied depending on the orientation of the gene specific primer (GSP) that was chosen. An aliquot of the double stranded cDNA was added to the following reagents: 10 μM Marathon cDNA adapter, 5×DNA ligation buffer, T4 DNA ligase. The reaction was incubated at 16° C. overnight and heat inactivated to terminate the reaction. PCR was performed by the addition of the following to the diluted double stranded cDNA pool: 10× cDNA PCR reaction buffer, 10 μM DNTP mix, 10 μM GSP, 10 μM AP1 primer (kit), 50× Advantage cDNA Polymerase Mix. Thermal Cycling conditions were 94° C. for 30 seconds, 5 cycles of 94° C. for 5 seconds, 72° C. for 4 minutes, 5 cycles of 94° C. for 5 seconds, 70° C. for 4 minutes, 23 cycles of 94° C. for 5 seconds, 68° C. for 4 minutes. After the first round of PCR was performed using the GSP to extend to the end of the adapter to create the adapter primer binding site, exponential amplification of the specific cDNA of interest was performed. Usually, a second, nested PCR was performed to provide specificity. The RACE product was analyzed on an agarose gel. Following excision from the gel and purification (GeneClean, BIO 101), the RACE product was then cloned into pCTNR (General Contractor DNA Cloning System, 5′-3′, Inc.) and sequenced to verify that the clone was specific to the gene of interest.

[0225] 2. Expression Analysis. To characterize the expression of genes mapping to the 20p13-p12 region, a series of experiments were performed. First, oligonucleotide primers were designed for use in the polymerase chain reaction (PCR) so that portions of a cDNA, EST, or genomic DNA could be amplified from a pool of DNA molecules or RNA population (RT-PCR). The PCR primers were used in a reaction containing genomic DNA to verify that they generated a product of the predicted size (based on the genomic sequence). A critical piece of data that is required when characterizing novel genes is the length, in nucleotides, of the processed transcript or messenger RNA (mRNA). Those skilled in the art primarily determine the length of an mRNA by Northern analysis (Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor N.Y. (1989)). Probes were generated using one of the methods described below. Briefly, sequence verified IMAGE consortium cDNA clones were digested with appropriate restriction endonucleases to release the insert. The restriction digest was electrophoresed on an agarose gel and the bands containing the insert were excised. The gel piece containing the DNA insert was placed in a Spin-X (Corning Costar Corporation, Cambridge, Mass. or Supelco spin column (Supelco Park, Pa.) and spun at high speed for 15 mins. The DNA was ethanol precipitated and resuspended in TE. Alternatively, PCR products obtained from genomic DNA or RT-PCR were also purified as described above. Inserts purified from IMAGE clones were random primer labelled (Feinberg and Vogelstein) to generate probes for hybridization. Probes from purified PCR products were generated by incorporation of a-³²P-dCTP in second round of PCR. Commercially available Multiple Tissue Northern blots (Clontech, Palo Alto, Calif.) were hybridized and washed under conditions recommended by the manufacturer. FIG. 16 depicts the Northern Analysis of Gene 216. As shown in the figure, various tissue sources showed expression of Gene 216.

[0226] 3. RT-PCR. RT-PCR was used as an alternate method to Northern blotting to detect mRNAs with low levels of expression. Total RNA from multiple human tissues was purchased from Clontech (Palo Alto, Calif.) and genomic DNA was removed from the total RNA by DNaseI digestion. The “Superscript Preamplification System for First strand cDNA synthesis” (Life Technologies, Gaithersburg, Md.) was used according to manufacturer's specifications with oligo(dT) or random hexamers to synthesize cDNA from the DNaseI treated total RNA. Gene specific primers were used to amplify the target cDNAs in a 30 μl PCR reaction containing 0.5 μl of first strand cDNA, 1 μl sense primer (10 μM), 1 μl antisense primer (10 μM), 3 μl dNTPs (2 mM), 1.2 μl MgCl₂ (25 mM), 3 μl 10×PCR buffer and 1 unit of Taq Polymerase (Perkin Elmer). The PCR reaction was initially denatured at 94° C. for 4 min, then 30 cycles of denaturation at 94° C. for 30 sec, annealing at 58° C. for 1 min and extension at 72° C. for 1 min, followed by a final extension at 72° C. for 7 min. PCR products were analyzed on agarose gels.

[0227] Three alternatively transcribed transcripts of Gene 216 were identified described as Gene 216a, isolated from lung cDNA library; Gene 216b, isolated from testes cDNA library; and 216c, predicted by Genscan (Burge and Karlin, J. Mol. Biol., 268:78-94); and their corresponding cDNA sequence are shown in FIGS. 3A-F, 4A-4F and 5A-5G, respectively. FIG. 6 shows a schematic of the exons of Gene 216a, Gene 216b, and 216c. FIGS. 7A-7B, 8A-8B, and 9A-9B depict the predicted exon/intron structure of Gene 216a, Gene 216b, and 216c, respectively.

[0228] H. Computational Biology Analysis

[0229] Multiple protein alignment of 19 Human a disintegrin-like and metalloproteinase-containing protein (ADAMs) and Gene 216 was performed using the GCG program PILEUP (Wisconsin Package Version 9.1 Genetics Computer Group (GCG), 1997). The alignment was based on the full amino acid sequence of the 19 ADAMs and Gene 216, and utilized a gap creation penalty of 12 and a gap extension penalty of 4. The results of the alignment generated two outputs: a phylogenetic tree known as a dendogram that shows relatedness and evolutionary diversity of the genes to each other (FIG. 10); and an amino acid sequence alignment of those genes (FIGS. 11A-11D).

[0230] Multiple protein alignment of the predicted mouse homolog of Gene 216 and the alternately spliced variants, Gene 216a, Gene 216b and Gene 216c (FIGS. 12A-12B) was performed in GeneWorks version 2.3 (IntelliGenetics). The alignment was based on the full amino acid sequence of the predicted mouse gene and Gene 216, and utilized a gap creation penalty of 12 and a gap extension penalty of 4.

[0231] The Kyte-Doolittle hydrophobicity plot (FIG. 13) was utilized in GeneWorks version 2.3 (IntelliGenetics). This algorithm measures the hydrophobicity across a protein, thus providing an indication of the probable location of regions of Gene 216 that may interact with the lipid bilayer of the cell membrane. The black bar with the letter “A” indicates the signal peptide sequence. The transmembrane domain is located by the black bar with the letter “B.”

[0232] I. Gene Analysis and Potential Function

[0233] The association of Gene 216 with asthma and other respiratory diseases is demonstrated as follows:

[0234] BLAST analysis against protein and nucleotide databases indicated that Gene 216 is likely to be a novel member of the ADAM gene family (Table 6). The ADAMs are zinc-dependent metalloproteinases, a growing gene family that currently contains 30 members. These genes have a complex domain organization that consists of a signal sequence, a propeptide, metalloprotease, disintegrin, cysteine-rich, and epidermal growth factor-like domains, a transmembrane region and a cytoplasmic tail. ADAMs have been implicated in many processes such as but not limited to, proteolysis in the secretory pathway and extracellular matrix, extra- and intra-cellular signaling, processing of plasma membrane proteins and procytokine conversion. TABLE 6 shows the top five hits when Gene 216 was compared against NR protein database using BLAST. Hit GenBank Locus Description Smallest Sum 1 U66003 Xenopus laevis (ADAM 13) 5.5e−166 2 AF019887 Mus musculus metalloprotease- 1.2e−139 disintegrin meltrin beta 3 AF134707 Homo sapiens disintegrin and 1.6e−139 metalloproteinase domain 19 (ADAM19) 4 S60257 Mouse mRNA for meltrin alpha 1.8e−121 5 AF023476 Homo sapiens meltrin- 4.9e−119 L precursor (ADAM12)

[0235] BAC RPCI-11_(—)1098L22 (207 kb) maps to chromosome 20p13-p12 and contains the genetic marker D20S867 located 12.12cM from the telomere of the p-arm of chromosome 20. Gene 216 spans 17 kb and maps within the BAC between nucleotides 91000 and 108000. The gene contains 21 exons (FIG. 6) and exhibits three probable alternatively spliced variants: Gene 216a, Gene 216b and Gene 216c (FIGS. 7A-7B, 8A-8B, and 9A-9B). Northern blot analysis of Gene 216 showed a 5.0 Kb transcript that was expressed in a wide variety of somatic tissues, including lung, brain, heart, skeletal muscle, colon, kidney, liver, small intestine, placenta, lymph, thymus and bone marrow (FIG. 14). The open reading frame (ORF) for Gene 216a is 2241 bp of the transcript and encodes 747 amino acids (FIGS. 3A-3F), for Gene 216b the ORF is 2364 bp of the transcript and encodes 788 amino acids (FIGS. 4A-4F) and for Gene 216c the ORF is 2550 bp of the transcript and encodes 850 amino acids (FIGS. 5A-5G).

[0236] The dendogram (FIG. 10) demonstrated that Gene 216 was probably most closely related to ADAM 12 and 19. The dendogram also indicated that 4 additional ADAMs were probably distantly related to Gene 216. Amino acid sequence alignment of these 6 ADAMs to Gene 216 (FIGS. 11A-11D) indicated regions of significant similarity that represented the domains which genes of this type possess. This alignment was determined by GCG (Wisconsin Package Version 9.1 Genetics Computer Group (GCG), 1997). The alignment was based on a gap creation penalty of 12 and gap extension penalty of 4. Arrows represent the likely position of the domains, boxed amino acid residues represent the consensus regions in Gene 216 with ADAMs and dashed boxed amino acids represents a putative SH₃ binding site.

[0237] Gene 216 contains a signal sequence (FIG. 13), which is also shared by most of the ADAMs (FIG. 11A). The presence of a signal sequence at the beginning of a protein helps to facilitate its transfer through the lipid bilayer.

[0238] The prodomain was identified through amino acid sequence alignment and by reference to publications describing ADAMs (Stone et al, J. Prot. Chem., 18:447-465 (1999), Primakov and Myles, TIG, 16:83-87 (2000)). All ADAMs possess a prodomain that contains a conserved cysteine residue (FIG. 11A). This conserved cysteine is involved in formation of an intramolecular complex with a zinc ion bound to the catalytic domain. The interaction serves to block the active site and inhibits proteolysis. Upon conformational change or enzymatic cleavage of the prodomain the cysteine is dissociated from the active site and the ADAM is activated. This activation mechanism is called the “cysteine switch”. The presence of the conserved domain suggests that Gene 216 has the ability to be activated by a conformational change or by unknown proteases.

[0239] All ADAMs also encode a highly conserved metalloprotease domain similar to the sequence (TMAHEIGHSLGLSHDPD) in Gene 216 (Table 7 and FIG. 11B). The 3 histidines (H) bind a zinc ion, the second glycine (G) allows a turn and the glutamic acid (E) is the catalytically active residue. This sequence is followed by a “Met turn”, a structure that folds back and stabilizes the interaction with zinc. The presence of the metalloprotease domain and the “Met turn” suggests that Gene 216 has proteolytic activity. TABLE 7 shows the top two hits when Gene 216 was compared against the motif database using Blimps. The dis- integrin and metalloproteinase domains were iden- tified. Description Strength Score AA# AA Sequence Disintegrins 1950 1597 377 CCfAhnCsLRPGAQCAh proteins GdCCvRC1KpAGaL CRqAMGDCD1PEfCT GTSshCPP Zinc 1173 1276 276 TMAHEIGHSLG metallo- peptidases

[0240] The disintegrin domains of the ADAMs are purported to be ligands for integrins and other receptors. The presence of this domain in Gene 216 (Table 7 and FIGS. 11B-11C), suggests that it also has adhesion activity.

[0241] It is also probable that Gene 216 contains a cysteine rich and EGF-like domains as do other ADAM genes (FIG. 11C and Stone et al, J. Prot. Chem., 18:447-465 (1999), Primakov and Myles, TIG, 16:83-87 (2000)).

[0242] In ADAMs the presence of a transmembrane domain, as shown in Gene 216, serves to function as a membrane anchor (FIGS. 11C-11D and 13). The cytoplasmic tail and a putative SH3 binding site are also present in Gene 216 (FIG. 11D and Stone et al, J. Prot. Chem., 18:447-465 (1999), Primakov and Myles, TIG, 16:83-87 (2000)). The transmembrane domain flanked by an EGF-like domain and a cytoplasmic tail is purported to play a role in signal transduction between the extracellular and intracellular space via cell-cell or cell-matrix interactions. Thus, Gene 216 is probably involved in signal transduction.

[0243] Gene 216 is most likely a novel member of the ADAM gene family which is part of a very large and relatively diverse superfamily called zinc-dependent metalloproteinases (Stone et al, J. Prot. Chem., 18:447-465 (1999)). Interestingly, the proteolytic release of TNF-α, an important proinflammatory cytokine in asthma, from the plasma membrane is catalyzed by TNF-α converting enzyme, a member of the ADAM gene family (TACE or ADAM-17). Excess of this protein can cause tissue damage leading to airway remodelling (Ohno et al, Am. J. Cell Mol. Biol., 16:212-219 (1997)). ADAMs that can release soluble plasma membrane-anchored cytokines, growth factors, receptors, adhesion molecules and enzymes are called sheddases (Primakov and Myles, TIG, 16:83-87 (2000)). Currently these include ADAM 9 (sheds the heparin-binding EGF-like growth factor), ADAM 10 (sheds a soluble form of Delta, a Notch ligand) and ADAM 17 (sheds TNF-α). The relationship and functional role of ADAMs to inflammatory responses suggests that Gene 216 is probably involved in the pathophysiology of asthma and other respiratory diseases.

[0244] In addition to respiratory diseases, Gene 216 is likely to be involved in obesity. Wilson et al. has shown that obesity may be linked to asthma (Arch. Intern. Med. 159: 2513-14 (1999)).

[0245] J. Identification of the Mouse Homolog To Gene 216

[0246] The mouse homolog of Gene 216 was identified by BLAST analysis of the ORF of Gene 216a against mouse dbEST. The nucleotide sequence of the mouse homolog is depicted in FIGS. 18A-18G and the corresponding amino acid is depicted in FIG. 19. The results identified three mouse ESTs that were partially homologous to the human sequence but were not 100% homologous to any known mouse ADAM genes. The three mouse ESTs were 100% homologous to a partially sequenced mouse BAC (BAC389B9-accession number AF155960). This BAC maps to mouse chromosome 2 which is syntenic with the human chromosome 20p13. The 47 Kb sequence was analyzed for any potential genes using Genscan. The results identified a gene that possessed an ORF of 2124 bp which encoded 707 amino acids. The amino acid sequence was compared against the protein database by BLAST analysis and it was found to have homology to mouse and human ADAM genes. The 707 amino acid sequence was aligned against the amino acid sequences of Gene 216a, 216b and 216c. The results showed the mouse amino acid sequence to have >50% identity at the protein level (FIGS. 12A-12B). Shaded areas represent identical and similar proteins; i.e. conserved regions. This result demonstrated that the mouse sequence was indeed the murine homolog of the human Gene 216, a probable novel member of the ADAM family.

[0247] K. Mutation Analysis

[0248] A combination of fluorescent single stranded confirmation polymorphism (SSCP) analysis (ABI) and DNA sequencing was used to identify and determine precisely the nature of the variant at the nucleotide level. Genomic structure was elucidated for Gene 216. Through combination of exon-PCR with direct genomic sequencing of BAC DNA was utilized. cDNA sequence and predicted exons from Genscan was compared to genomic sequence to determine the precise exon-intron junctions. SSCP analysis was used to screen individual DNA for variants. Briefly, polymerase chain reaction (PCR) was used to generate templates from asthmatic individuals that showed increased sharing for the 20p13-p12 chromosomal region and contributed towards linkage. Non-asthmatic individuals were used as controls. Enzymatic amplification of Gene 216 was accomplished using PCR with oligonucleotides flanking each exon as well as the putative 5′ region. The primers were chosen to amplify each exon as well as 15 or more base pairs within each intron on either side of the splice site. The forward and the reverse primers had two different dye colors to allow analysis of each strand and confirm variants independently. Standard PCR assays were utilized for each exon primer pair following optimization. Buffer and cycling conditions were specific to each primer set. The products were denatured using a formamide dye and electrophoresed on non-denaturing acrylamide gels with varying concentrations of glycerol (at least two different glycerol concentrations).

[0249] Comparative DNA sequencing was used to determine the sequence changes in Gene 216 in individuals found to be polymorphic by SSCP. Variants detected in the initial set of asthmatic and normal individuals were subject to fluorescent sequencing (ABI) using a standard protocol described by the manufacturer (Perkin Elmer, Palo Alto, Calif.) Sequence conserved variants were then re-examined in a larger set of asthmatic individuals and normal control/non-asthmatics to assess the frequency of the polymorphisms. Statistical analysis was performed to determine if the variant showed an increased prevalence in asthmatics as compared to non-asthmatics and hence was associated with the asthma phenotype.

[0253] FIGS. 15A-15B, 16A-16B and 17A-17B illustrate the three different transcripts of Gene 216. Using an in-house program called gene_view; the genomic structure of the gene is diagrammatically shown.

[0254] The polymorphic sites discovered within the cDNA of Gene 216a, Gene 216b and 216c are underlined in FIGS. 3A-3F, 4A-4F and 5A-5G, respectively. The corresponding amino acid position of these polymorphisms are also underlined in FIGS. 3A-3F, 4A-4F and 5A-5G.

[0255] L. Restriction Fragment Length Polymorphism (RFLP Assay) and Allele Specific Oligonucleotide Analysis (ASO Assay)

[0256] To identify other individuals with the polymorphisms listed in Table 10, RPLP assay and ASA were performed.

[0257] 1. RFLP Assay. The amplicon, containing the polymorphism, was PCR amplified using primers that were used to generate a fragment for sequencing (sequencing primers) or SSCP (SSCP primers). The appropriate population of individuals was PCR amplified in 96 well microtitre plates.

[0258] Enzymes were purchased from New England Biolabs (NEB). The restriction cocktail containing the appropriate enzyme for the particular polymorphism is added to the PCR product. The reaction is incubated at the appropriate temperature according to the manufacturer's recommendations (NEB) for two to three hours, followed by a 4° C. incubation. After digestion, the reactions were size fractionated using the appropriate agarose gel depending on the assay specifications (2.5%, 3%, or metaphor). Gels are electrophoresed in 1×TBE Buffer at 170 Volts for approximately two hours.

[0259] The gel is illuminated using ultraviolet light and the image is saved as a Kodak 1D file. Using the Kodak 1D image analysis software, the images are scored and the data is exported to EXCEL.

[0260] 2. ASO Assay. The amplicon, containing the polymorphism, was PCR amplified using primers that were used to generate a fragment for sequencing (sequencing primers) or SSCP (SSCP primers). The appropriate population of individuals was PCR amplified in 96 well microtitre plates and re-arrayed into 384 well microtitre plates using a Tecan Genesis RSP200. The amplified products were loaded onto 2% agarose gels and size fractionated at 150V for 5 minutes. The DNA was transferred from the gel to Hybond N+ nylon membrane (Amersham-Pharmacia) using a Vacuum blotter (Bio-Rad). The filter containing the blotted PCR products was transferred to a dish containing 300 mls of pre-hybridization solution (5×SSPE {pH7.4}, 2% SDS, 5× Denhardts). The filter was left in the pre-hybridization solution at 40° C. for >1 hour. After pre-hybridization, 10 mls of the pre-hybridization solution and the filter were transferred to a washed glass bottle. The allele specific oligonucleotides (ASO) were designed with the polymorphism in the middle. The size of the oligonucleotide was dependent upon the GC content of the sequence around the polymorphism. Those ASOs that had a G or C polymorphism were designed so that the Tm was between 54-56° C. and those that had an A or T variance were designed so that the Tm was between 60-64° C. All oligonucleotides were phosphate free at the 5′end and purchased from Gibco BRL. For each polymorphism 2 ASOs were designed: one for each variant.

[0261] The two ASOs that represented the polymorphism were resuspended at a concentration of 1 μg/μl and separately end-labeled with γ-ATP³² (6000 Ci/mmol) (NEN) using T4 polynucleotide kinase according to manufacturer recommendations (NEB). The end-labeled products were removed from the unincorporated γ-ATP³² by passing the reactions through Sephadex G-25 columns according to manufacturers recommendation (Amersham-Pharmacia). The entire end-labeled product of one ASO was added to the bottle containing the appropriate filter and 10 mls of hybridization solution. The hybridization reaction was placed in a rotisserie oven (Hybaid) and left at 40° C. for a minimum of 4 hours. The other ASO was stored at −20° C.

[0262] After the prerequisite hybridization time had elapsed, the filter was removed from the bottle and transferred to 1 liter of wash solution (0.1×SSPE {pH7.4}, 0.1% SDS) pre-warmed to 45° C. After 15 minutes the filter was transferred to another liter of wash solution (0.1×SSPE {pH7.4}, 0.1% SDS) pre-warmed to 50° C. After 15 minutes the filter was wrapped in Saran, placed in an autoradiograph cassette and an X-ray film (Kodak) placed on top of the filter. Depending on the efficiency of the end-labeling reaction of the ASO and its hybridization to the filter an image would be observed on the film within an hour. After an image had been captured on film for the 50° C. wash, the process was repeated for wash steps at 55° C., 60° C. and 65° C. The image that captured the best result was used.

[0263] The ASO was removed from the filter by adding 1 liter of boiling strip solution (0.1×SSPE {pH7.4}, 0.1% SDS). This was repeated two more times. After removing the ASO the filter was pre-hybridized in 300 mls of pre-hybridization solution (5×SSPE {pH7.4}, 2% SDS, 5× Denhardts) at 40° C. for >1 hour. The second end-labeled ASO corresponding to the other variant was removed from storage at −20° C. and thawed to room temperature. The filter was placed into a glass bottle along with 10 mls of hybridization solution and the entire end-labeled product of the second ASO. The hybridization reaction was placed in a rotisserie oven (Hybaid) and left at 40° C. for a minimum of 4 hours. After the hybridization, the filter was washed at various temperatures and images captured on film as described above.

[0264] The two films that best captured the allele specific assay with the two ASOs were converted into digital images by scanning them into Adobe PhotoShop. These images were overlaid against each other in Graphic Converter and then scored and stored in FileMaker Pro 4.0.

[0265] M. Association Study Analysis

[0266] In order to determine whether mutations in candidate genes are responsible for the asthma phenotype, association studies are performed using a case-control study design. To avoid issues of population admixture which can bias case-control studies, the unaffected controls were collected in both the US and the UK. A total of three hundred controls were collected, 200 in the UK and 100 in the US. Inclusion into the study required that the control individual was negative for asthma, as determined by self report of never having asthma, has no first degree relatives with asthma, and was negative for eczema and symptoms indicative of atopy within the past 12 months. Data from an abbreviated questionnaire similar to that administered to the affected sib pair families were collected. Results from skin prick tests to 4 common allergens were also collected. The results of the skin prick test were used to select a subset of control that were most likely to be asthma and atopy negative.

[0267] A subset of unrelated cases are selected from the affected sib pair families based on the evidence for linkage at the chromosomal location of interest. One affected sib from families demonstrating identity-by-decent (IBD) at the appropriate marker loci is selected. In the selection criteria, preference is given to families with multiple affected sibs all of whom are concordant at the marker locus as well as to families where affected and unaffected sibs are discordant.

[0268] Since the appropriate cases may vary for each SNP, a larger collection of individuals who are jointly IBD across a larger interval are genotyped and a subset used in the analyses. For each polymorphism, the frequency of the alleles in the control and case populations is compared using a Fisher exact test. It is expected that a mutation increasing susceptibility to the disease would be more prevalent in the cases than in the controls, while a protective mutation should be more prevalent in the control group. Similarly, the genotype frequencies of the SNPs are compared between cases and controls. P-values are computed for both the allele and genotype frequencies. A small p-value, is indicative of an association between the SNPs and the disease phenotype. The analysis is repeated for the US and UK population separately, to adjust for the possibility of genetic heterogeneity.

[0269] 1. Association Test with Individual SNPs

[0270] Gene 216 has 21 exons spanning 17 kb. Seventeen exons have been completely screened by SSCP, of which ten exons are polymorphic. Seven of the 17 identified SNPs reside in the coding portion of the gene, six of which result in amino acid changes. The structure of the gene and the distribution of SNPs are shown in FIGS. 15A-15B, 16A-16B and 17A-17B.

[0271] Statistical analyses for all seven SNPs are presented in Table 11. Column one list the exon containing the SNP of interest. The control (“CNTL”) allele frequency and sample size (“N”) are in columns two and three. The affected individuals (“CASE”) allele frequency and sample size (“N”) are listed in columns four and five. The sixth column contains the significance value level of comparison between the control allele frequencies and the case allele frequencies.

[0272] The results demostrate that five SNPs have allelic frequencies significantly different in the cases versus the controls in either the US or UK samples. In the US population, two SNPs in exon R were more frequent in the cases (20% and 29%, respectively) than in the control population (8% and 5%, respectively), and the differences were statistically significance (p=0.035 and p=0.0031). Both of these mutations resulted in amino acid changes; a methionine to threonine in the first SNP while a serine replaced proline in the second SNP. In the UK and the combined sample, two SNPs in the adjacent exon (Q) reached statistical significant. A synonymous SNP was present in 27% of alleles of the controls and in only 15% for the cases for the UK population (26% vs 19% in combined sample), a difference which is highly significant (p=0.002 for UK sample, p=0.043 for combined sample). In the same exon, a SNP producing an amino acid change (a valine to an isoleucine) was observed more frequently in the controls than in the cases in the UK population (11% vs 5%, p=0.027), and this was also true for the combined sample (11% vs 5%, p=0.021). In addition, a SNP just outside exon O reached statistical significance in both the UK and combined sample (p=0.028 for UK sample, 14% in controls versus 8% of cases; p=0.029 in combined sample, 14% of cases versus 9% in controls).

[0273] 2. Haplotype Analyses

[0274] In addition to analyzing individual SNPs, haplotype analyses were used to compare haplotype frequencies between the case and control groups. For these purposes, haplotypes for all polymorphisms are defined as those that lead to amino acid changes for a particular gene. The haplotypes are constructed using a maximum likelihood approach. The estimated frequency of each haplotype is compared between cases and controls by a permutation test. An overall comparison of the distribution of all haplotypes between the two groups is also performed.

[0275] Haplotype analyses were performed on Gene 216. The results are shown in Table 12. Column one is the amino acid sequence of the haplotype. The haplotype frequency in the control and the case is within columns two and three, respectively. Column four contains the significance of the difference of the case and the control. The most frequent haplotype was present more often in the controls than in the cases (p=0.038), and the second most frequent haplotype (24% in cases) was only present in about 8% of the controls (p=0.004). In the US and UK populations, a trend towards statistical significance was observed when comparing the haplotype distribution between the cases and controls (p=0.066 for US, p=0.093 for UK).

[0277] II. Preparation of Nucleic Acids, Vectors, Transformations and Host Cells

[0278] The nucleic acids of this invention can be produced in large quantities by replication in a suitable host cell. Natural or synthetic nucleic acid fragments, comprising at least ten contiguous bases coding for a desired peptide or polypeptide can be incorporated into recombinant nucleic acid constructs, usually DNA constructs, capable of introduction into and replication in a prokaryotic or eukaryotic cell. Usually the nucleic acid constructs will be suitable for replication in a unicellular host, such as yeast or bacteria, but may also be intended for introduction to (with and without integration within the genome) cultured mammalian or plant or other eukaryotic cells, cell lines, tissues, or organisms. The purification of nucleic acids produced by the methods of the present invention is described, for example, in Sambrook et al, Molecular Cloning, A Laboratory Manual, 2nd Ed. (Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1989) or Ausubel et al, Current Protocols in Molecular Biology, J. Wiley and Sons, NY (1992).

[0279] The nucleic acids of the present invention can also be produced by chemical synthesis, e.g., by the phosphoramidite method described by Beaucage et al, Tetra. Letts., 22:1859-1862 (1981) or the triester method according to Matteucci, et al, J. Am. Chem. Soc., 103:3185 (1981), and can performed on commercial, automated oligonucleotide synthesizers. A double-stranded fragment may be obtained from the single-stranded product of chemical synthesis either by synthesizing the complementary strand and annealing the strands together under appropriate conditions or by adding the complementary strand using DNA polymerase with an appropriate primer sequence.

[0280] These nucleic acids can encode full-length variant forms of proteins as well as the naturally-occurring protein. The variant proteins (which could be especially useful for detection and treatment of disorders) will have the variant amino acid sequences encoded by the polymorphisms described in Table 10, when said polymorphisms are read so as to be in-frame with the full-length coding sequence of which it is a component.

[0281] Nucleic acid constructs prepared for introduction into a prokaryotic or eukaryotic host will comprise a replication system recognized by the host, including the intended nucleic acid fragment encoding the selected protein or polypeptide, and will preferably also include transcription and translational initiation regulatory sequences operably linked to the protein encoding segment. Expression vectors may include, for example, an origin of replication or autonomously replicating sequence (ARS) and expression control sequences, a promoter, an enhancer and necessary processing information sites, such as ribosome-binding sites, RNA splice sites, polyadenylation sites, transcriptional terminator sequences, and mRNA stabilizing sequences. Secretion signals are also included, where appropriate, whether from a native Gene 216 protein or from other receptors or from secreted proteins of the same or related species, which allow the protein to cross and/or lodge in cell membranes, and thus attain its functional topology, or be secreted from the cell. Such vectors may be prepared by means of standard recombinant techniques well known in the art and discussed, for example, in Sambrook et al, Molecular Cloning. A Laboratory Manual, 2nd Ed. (Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1989) or Ausubel et al., Current Protocols in Molecular Biology, J. Wiley and Sons, NY (1992).

[0282] An appropriate promoter and other necessary vector sequences will be selected so as to be functional in the host, and will include, when appropriate, those naturally associated with Gene 216 gene. Examples of workable combinations of cell lines and expression vectors are described in Sambrook et al, Molecular Cloning. A Laboratory Manual, 2nd Ed. (Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1989) or Ausubel et al, Current Protocols in Molecular Biology, J. Wiley and Sons, NY (1992). Many useful vectors are known in the art and can be obtained from such vendors as Stratagene (supra), New England BioLabs, Beverly, Mass., U.S.A, Promega Biotech, and other biotechnology product suppliers. Promoters such as the trp, lac and phage promoters, tRNA promoters and glycolytic enzyme promoters may be used in prokaryotic hosts. Useful yeast promoters include promoter regions for metallothionein, 3-phosphoglycerate kinase or other glycolytic enzymes such as enolase or glyceraldehyde-3-phosphate dehydrogenase, enzymes responsible for maltose and galactose utilization, and others. Vectors and promoters suitable for use in yeast expression are further described in EP 73,675A. Appropriate non-native mammalian promoters might include the early and late promoters from SV40 (Fiers et al, Nature, 273:113 (1978)) or promoters derived from murine Moloney leukemia virus, mouse tumor virus, avian sarcoma viruses, adenovirus II, bovine papilloma virus or polyoma. In addition, the construct may be joined to an amplifiable gene (e.g., DHFR) so that multiple copies of the gene may be made. For appropriate enhancer and other expression control sequences, see also Enhancers and Eukaryotic Gene Expression, Cold Spring Harbor Press, Cold Spring Harbor, N.Y. (1983). While such expression vectors may replicate autonomously, they may also replicate by being inserted into the genome of the host cell, by methods well known in the art.

[0283] Expression and cloning vectors will likely contain a selectable marker, a gene encoding a protein necessary for survival or growth of a host cell transformed with the vector. The presence of this gene ensures growth of only those host cells which express the inserts. Typical selection genes encode proteins that a) confer resistance to antibiotics or other toxic substances, e.g. ampicillin, neomycin, methotrexate, etc.; b) complement auxotrophic deficiencies, or c) supply critical nutrients not available from complex media, e.g., the gene encoding D-alanine racemase for Bacilli. The choice of the proper selectable marker will depend on the host cell, and appropriate markers for different hosts are well known in the art.

[0284] The vectors containing the nucleic acids of interest can be transcribed in vitro, and the resulting RNA introduced into the host cell by well-known methods, e.g., by injection (see, Kubo et al, FEBS Letts. 241:119 (1988)), or the vectors can be introduced directly into host cells by methods well known in the art, which vary depending on the type of cellular host, including electroporation; transfection employing calcium chloride, rubidium chloride, calcium phosphate, DEAE-dextran, or other substances; microprojectile bombardment; lipofection; infection (where the vector is an infectious agent, such as a retroviral genome); and other methods. See generally, Sambrook et al., 1989 and Ausubel et al., 1992. The introduction of the nucleic acids into the host cell by any method known in the art, including those described above, will be referred to herein as “transformation.” The cells into which have been introduced nucleic acids described above are meant to also include the progeny of such cells.

[0285] Large quantities of the nucleic acids and proteins of the present invention may be prepared by expressing the Gene 216 nucleic acids or portions thereof in vectors or other expression vehicles in compatible prokaryotic or eukaryotic host cells. The most commonly used prokaryotic hosts are strains of Escherichia coli, although other prokaryotes, such as Bacillus subtilis or Pseudomonas may also be used.

[0286] Mammalian or other eukaryotic host cells, such as those of yeast, filamentous fungi, plant, insect, or amphibian or avian species, may also be useful for production of the proteins of the present invention. Propagation of mammalian cells in culture is per se well known. See, Jakoby and Pastan (eds.), Cell Culture. Methods in Enzymology, volume 58, Academic Press, Inc., Harcourt Brace Jovanovich, N.Y., (1979)). Examples of commonly used mammalian host cell lines are VERO and HeLa cells, Chinese hamster ovary (CHO) cells, and WI38, BHK, and COS cell lines, although it will be appreciated by the skilled practitioner that other cell lines may be appropriate, e.g., to provide higher expression desirable glycosylation patterns, or other features.

[0287] Clones are selected by using markers depending on the mode of the vector construction. The marker may be on the same or a different DNA molecule, preferably the same DNA molecule. In prokaryotic hosts, the transformant may be selected, e.g., by resistance to ampicillin, tetracycline or other antibiotics. Production of a particular product based on temperature sensitivity may also serve as an appropriate marker.

[0288] Prokaryotic or eukaryotic cells transformed with the nucleic acids of the present invention will be useful not only for the production of the nucleic acids and proteins of the present invention, but also, for example, in studying the characteristics of Gene 216 proteins.

[0289] Antisense nucleic acid sequences are useful in preventing or diminishing the expression of Gene 216 gene, as will be appreciated by one skilled in the art. For example, nucleic acid vectors containing all or a fragment Gene 216 gene, complementary sequences of the former, or other sequences from the 20p13-p12 region may be placed under the control of a promoter in an antisense orientation and introduced into a cell. Such fragments can be 16 or more nucleotides in length. Expression of such an antisense construct within a cell will interfere with Gene 216 transcription and/or translation and/or replication.

[0290] The probes and primers based on the Gene 216 gene sequences disclosed herein are used to identify homologous Gene 216 gene sequences and proteins in other species. These Gene 216 gene sequences and proteins are used in the diagnostic/prognostic, therapeutic and drug screening methods described herein for the species from which they have been isolated.

[0291] III. Protein Expression and Purification

[0292] Expression and purification of the Gene 216 protein of the invention can be performed essentially as outlined below. To facilitate the cloning, expression and purification of membrane and secreted protein from the 20p13-p12, a gene expression system, such as the pET System (Novagen), for cloning and expression of recombinant proteins in E. coli is selected. Also, a DNA sequence encoding a peptide tag, the His-Tap, is fused to the 3′ end of DNA sequences of interest to facilitate purification of the recombinant protein products. The 3′ end is selected for fusion to avoid alteration of any 5′ terminal signal sequence.

[0293] Nucleic acids chosen, for example, from the nucleic acids set forth SEQ ID NO:1-SEQ ID NO:3, or SEQ ID NO:7 (FIGS. 20A-20G) for cloning the genes are prepared by polymerase chain reaction (PCR). Synthetic oligonucleotide primers specific for the 5′ and 3′ ends of the nucleotide sequences are designed and purchased from Life Technologies (Gaithersburg, Md.). All forward primers (specific for the 5′ end of the sequence) are designed to include an NcoI cloning site at the 5′ terminus. These primers are designed to permit initiation of protein translation at the methionine residue encoded within the NcoI site followed by a valine residue and the protein encoded by the DNA sequence. All reverse primers (specific for the 3′ end of the sequence) include an EcoRI site at the 5′ terminus to permit cloning of the sequence into the reading frame of the pET-28b. The pET-28b vector provides a sequence encoding an additional 20 carboxyl-terminal amino acids including six histidine residues (at the C-terminus), which comprise the histidine affinity tag.

[0294] DNA prepared from the 20p13-p12 region is used as the source of template DNA for PCR amplification (Ausubel et al, Current Protocols in Molecular Biology, John Wilty & Sons (1994)). To amplify a DNA sequence containing the nucleotide sequence, c DNA (50 ng) is introduced into a reaction vial containing 2 mM MgCl₂, 1 micromolar synthetic oligonucleotide primers (forward and reverse primers) complementary to and flanking a defined 20p13-p12 region, 0.2 mM of each of deoxynucleotide triphosphate, dATP, dGTP, dCTP, dTTP and 2.5 units of heat stable DNA polymerase (Amplitaq, Roche Molecular Systems, Inc., Branchburg, N.J.) in a final volume of 100 microliters.

[0295] Upon completion of thermal cycling reactions, each sample of amplified DNA is purified using the Qiaquick Spin PCR purification kit (Qiagen, Gaithersburg, Md.). All amplified DNA samples are subjected to digestion with the restriction endonucleases, e.g., NcoI and EcoRI (New England BioLabs, Beverly, Mass., U.S.A.) (Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994)). DNA samples are then subjected to electrophoresis on 1.0% NuSeive (FMC BioProducts, Rockland, Me.) agarose gels. DNA is visualized by exposure to ethidium bromide and long wave UV irradiation. DNA contained in slices isolated from the agarose gel are purified using the Bio 101 GeneClean Kit protocol (Bio 101, Vista, Calif.).

[0296] The pET-28b vector is prepared for cloning by digestion with restriction endonucleases, e.g., NcoI and EcoRI (New England BioLabs, Beverly, Mass.) (Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994)). The pET-28a vector, which encodes the histidine affinity tag that can be fused to the 5′ end of an inserted gene, is prepared by digestion with appropriate restriction endonucleases.

[0297] Following digestion, DNA inserts are cloned (Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994)) into the previously digested pET-28b expression vector. Products of the ligation reaction are then used to transform the BL21 strain of E. coli (Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994)) as described below.

[0298] Competent bacteria, E. coli strain BL21 or E. coli strain BL21 (DE3), are transformed with recombinant pET expression plasmids carrying the cloned sequence according to standard methods (Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994)). Briefly, 1 microliter of ligation reaction is mixed with 50 microliters of electrocompetent cells and subjected to a high voltage pulse, after which samples were incubated in 0.45 ml SOC medium (0.5% yeast extract, 2.0% tryptone, 10 mM NaCl, 2.5 mM KCl, 10 mM MgCl₂, 10 mM MgSO₄ and 20 mM glucose) at 37° C. with shaking for 1 hour. Samples are then spread on LB agar plates containing 25 μg/ml kanamycin sulfate for growth overnight. Transformed colonies of BL21 are then picked and analyzed to evaluate cloned inserts, as described below.

[0299] Individual BL21 clones transformed with recombinant pET-28b 20p13-p12 region nucleotide sequences are analyzed by PCR amplification of the cloned inserts using the same forward and reverse primers specific for the 20p13-p12 region sequences that are used in the original PCR amplification cloning reactions. Successful amplification verifies the integration of the sequence in the expresssion vector (Ausubel et al, Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (1994)).

[0300] Individual clones of recombinant pET-28b vectors carrying properly cloned 20p13-p 12 region nucleotide sequences are picked and incubated in 5 ml of LB broth plus 25 μg/ml kanamycin sulfate overnight. The following day plasmid DNA is isolated and purified using the Qiagen plasmid purification protocol (Qiagen Inc., Chatsworth, Calif.).

[0301] The pET vector can be propagated in any E. coli K-12 strain, e.g., HMS174, HB101, JM109, DH5 and the like, for purposes of cloning or plasmid preparation. Hosts for expression include E. coli strains containing a chromosomal copy of the gene for T7 RNA polymerase. These hosts are lysogens of bacteriophage DE3, a lambda derivative that carries the lacI gene, the lacUV5 promoter and the gene for T7 RNA polymerase. T7 RNA polymerase is induced by addition of isopropyl-β-D-thiogalactoside (IPTG), and the T7 RNA polymerase transcribes any target plasmid containing a functional T7 promoter, such as pET-28b, carrying its gene of interest. Strains include, for example, BL21(DE3) (Studier et al, Meth. Enzymol., 185:60-89 (1990)).

[0302] To express the recombinant sequence, 50 ng of plasmid DNA are isolated as described above to transform competent BL21(DE3) bacteria as described above (provided by Novagen as part of the pET expression kit). The lacZ gene (β-galactosidase) is expressed in the pET-System as described for the 20p13-p12 region recombinant constructions. Transformed cells were cultured in SOC medium for 1 hour, and the culture is then plated on LB plates containing 25 μg/ml kanamycin sulfate. The following day, the bacterial colonies are pooled and grown in LB medium containing kanamycin sulfate (25 μg/ml) to an optical density at 600 nM of 0.5 to 1.0 O.D. units, at which point 1 mM IPTG was added to the culture for 3 hours to induce gene expression of the 20p13-p12 region recombinant DNA constructions.

[0303] After induction of gene expression with IPTG, bacteria are collected by centrifugation in a Sorvall RC-3B centrifuge at 3500×g for 15 minutes at 4° C. Pellets are resuspended in 50 ml of cold mM Tris-HCl, pH 8.0, 0.1 M NaCl and 0.1 mM EDTA (STE buffer). Cells are then centrifuged at 2000×g for 20 minutes at 4° C. Wet pellets are weighed and frozen at −80° C. until ready for protein purification.

[0304] A variety of methodologies known in the art can be used to purify the isolated proteins (Coligan et al, Current Protocols in Protein Science, John Wiley & Sons (1995)). For example, the frozen cells can be thawed, resuspended in buffer and ruptured by several passages through a small volume microfluidizer (Model M-110S, Microfluidics International Corp., Newton, Mass.). The resultant homogenate is centrifuged to yield a clear supernatant (crude extract) and, following filtration, the crude extract is fractioned over columns. Fractions are monitored by absorbance at OD₂₈₀ nm and peak fractions may be analyzed by SDS-PAGE.

[0305] The concentrations of purified protein preparations are quantified spectrophotometrically using absorbance coefficients calculated from amino acid content (Perkins, Eur. J. Biochem., 157:169-180 (1986)). Protein concentrations are also measured by the method of Bradford, Anal. Biochem., 72:248-254 (1976) and Lowry et al, J. Biol. Chem., 193:265-275 (1951) using bovine serum albumin as a standard.

[0306] SDS-polyacrylamide gels of various concentrations are purchased from BioRad (Hercules, Calif.), and stained with Coomassie blue. Molecular weight markers may include rabbit skeletal muscle myosin (200 kDa), E. coli P-galactosidase (116 kDa), rabbit muscle phosphorylase B (97.4 kDa), bovine serum albumin (66.2 kDa), ovalbumin (45 kDa), bovine carbonic anyhdrase (31 kDa), soybean trypsin inhibitor (21.5 kDa), egg white lysozyme (14.4 kDa) and bovine aprotinin (6.5 kDa).

[0307] Proteins can also be isolated by other conventional means of protein biochemistry and purification to obtain a substantially pure product, i.e., 80, 95, or 99% free of cell component contaminants, as described in Jacoby, Methods in Enzymology, Vol. 104, Academic Press, New York (1984); Scoopes, Protein Purification, Principles and Practice, 2^(nd) Ed., Springer-Verlag, New York (1987); and Deutscher (ed.), Guide to Protein Purification, Methods in Enzymology, Vol. 182 (1990). If the protein is secreted, it can be isolated from the supernatant in which the host cell is grown; otherwise, it can be isolated from a lysate of the host cells.

[0308] Once a sufficient quantity of the desired protein has been obtained, it may be used for various purposes. One use of the protein or polypeptide is the production of antibodies specific for binding. These antibodies may be either polyclonal or monoclonal, and may be produced by in vitro or in vivo techniques well known in the art. Monoclonal antibodies to epitopes of any of the peptides identified and isolated as described can be prepared from murine hybridomas (Kohler, Nature, 256:495 (1975)). In summary, a mouse is inoculated with a few micrograms of protein over a period of two weeks. The mouse is then sacrificed. The cells that produce antibodies are then removed from the mouse's spleen. The spleen cells are then fused with polyethylene glycol with mouse myeloma cells. The successfully fused cells are diluted in a microtiter plate and growth of the culture is continued. The amount of antibody per well is measured by immunoassay methods such as ELISA (Engvall, Meth. Enzymol., 70:419 (1980)). Clones producing antibody can be expanded and further propagated to produce protein antibodies. Other suitable techniques involve in vitro exposure of lymphocytes to the antigenic polypeptides, or alternatively, to selection of libraries of antibodies in phage or similar vectors. See Huse et al, Science, 246:1275-1281 (1989). For additional information on antibody production see Davis et al, Basic Methods in Molecular Biology, Elsevier, NY, Section 21-2 (1989). Such antibodies are particularly useful in diagnostic assays for detection of variant protein forms, or as an active ingredient in a pharmaceutical composition.

[0309] III. Transformed Hosts, Development of Pharmaceuticals and Research Tools

[0310] Cells and animals that carry the Gene 216 gene can be used as model systems to study and test for substances that have potential as therapeutic agents. The cells are typically cultured mesenchymal stem cells. These may be isolated from individuals with somatic or germline Gene 216 gene. Alternatively, the cell line can be engineered to carry the Gene 216 genes, as described above. After a test substance is applied to the cells, the transformed phenotype of the cell is determined. Any trait of transformed cells can be assessed, including respiratory diseases including asthma, atopy, and response to application of putative therapeutic agents.

[0311] IV. Diagnostic Applications

[0312] As discussed herein, chromosomal region 20p13-p12 has been genetically linked to a variety of diseases and disorders. The inventors provide nucleic acids and SNPs which can be useful in diagnosing individuals with chromosomal abnormalities linked to these diseases.

[0313] Antibody-based diagnostic methods: The invention provides methods for detecting disease-associated antigenic components in a biological sample, which methods comprise the steps of: (i) contacting a sample suspected to contain a disease-associated antigenic component with an antibody specific for an disease-associated antigen, extracellular or intracellular, under conditions in which a stable antigen-antibody complex can form between the antibody and disease-associated antigenic components in the sample; and (ii) detecting any antigen-antibody complex formed in step (i) using any suitable means known in the art, wherein the detection of a complex indicates the presence of disease-associated antigenic components in the sample. It will be understood that assays that utilize antibodies directed against sequences previously unidentified, or previously unidentified as being disease-associated, which sequences are disclosed herein, are within the scope of the invention.

[0314] Many immunoassay formats are known in the art, and the particular format used is determined by the desired application. An immunoassay can use, for example, a monoclonal antibody directed against a single disease-associated epitope, a combination of monoclonal antibodies directed against different epitopes of a single disease-associated antigenic component, monoclonal antibodies directed towards epitopes of different disease-associated antigens, polyclonal antibodies directed towards the same disease-associated antigen, or polyclonal antibodies directed towards different disease-associated antigens. Protocols can also, for example, use solid supports, or may involve immunoprecipitation.

[0315] Typically, immunoassays use either a labeled antibody or a labeled antigenic component (e.g., that competes with the antigen in the sample for binding to the antibody). Suitable labels include without limitation enzyme-based, fluorescent, chemiluminescent, radioactive, or dye molecules. Assays that amplify the signals from the probe are also known, such as, for example, those that utilize biotin and avidin, and enzyme-labeled immunoassays, such as ELISA assays.

[0316] Kits suitable for antibody-based diagnostic applications typically include one or more of the following components:

[0317] (i) Antibodies: The antibodies may be pre-labeled; alternatively, the antibody may be unlabeled and the ingredients for labeling may be included in the kit in separate containers, or a secondary, labeled antibody is provided; and

[0318] (ii) Reaction components: The kit may also contain other suitably packaged reagents and materials needed for the particular immunoassay protocol, including solid-phase matrices, if applicable, and standards.

[0319] The kits referred to above may include instructions for conducting the test. Furthermore, in preferred embodiments, the diagnostic kits are adaptable to high-throughput and/or automated operation.

[0320] Nucleic-acid-based diagnostic methods: The invention provides methods for detecting disease-associated nucleic acids in a sample, such as in a biological sample, which methods comprise the steps of: (i) contacting a sample suspected to contain a disease-associated nucleic acid with one or more disease-associated nucleic acid probes under conditions in which hybrids can form between any of the probes and disease-associated nucleic acid in the sample; and (ii) detecting any hybrids formed in step (i) using any suitable means known in the art, wherein the detection of hybrids indicates the presence of the disease-associated nucleic acid in the sample. To detect disease-associated nucleic acids present in low levels in biological samples, it may be necessary to amplify the disease-associated sequences or the hybridization signal as part of the diagnostic assay. Techniques for amplification are known to those of skill in the art.

[0321] Disease-associated nucleic acids useful as probes in diagnostic methods include oligonucleotides at least about 15 nucleotides in length, preferably at least about 20 nucleotides in length, and most preferably at least about 25-55 nucleotides in length, that hybridize specifically with one or more disease-associated nucleic acids.

[0322] A sample to be analyzed, such as, for example, a tissue sample, may be contacted directly with the nucleic acid probes. Alternatively, the sample may be treated to extract the nucleic acids contained therein. It will be understood that the particular method used to extract DNA will depend on the nature of the biological sample. The resulting nucleic acid from the sample may be subjected to gel electrophoresis or other size separation techniques, or, the nucleic acid sample may be immobilized on an appropriate solid matrix without size separation.

[0323] Kits suitable for nucleic acid-based diagnostic applications typically include the following components:

[0324] (i) Probe DNA: The probe DNA may be prelabeled; alternatively, the probe DNA may be unlabeled and the ingredients for labeling may be included in the kit in separate containers; and

[0325] (ii) Hybridization reagents: The kit may also contain other suitably packaged reagents and materials needed for the particular hybridization protocol, including solid-phase matrices, if applicable, and standards.

[0326] In cases where a disease condition is suspected to involve an alteration of the disease gene, specific oligonucleotides may be constructed and used to assess the level of disease mRNA in cells affected or other tissue affected by the disease.

[0327] For example, to test whether a person has a disease gene, polymerase chain reaction can be used. Two oligonucleotides are synthesized by standard methods or are obtained from a commercial supplier of custom-made oligonucleotides. The length and base composition are determined by standard criteria using the Oligo 4.0 primer Picking program (Wojchich Rychlik, 1992). One of the oligonucleotides is designed so that it will hybridize only to the disease gene DNA under the PCR conditions used. The other oligonucleotide is designed to hybridize a segment of genomic DNA such that amplification of DNA using these oligonucleotide primers produces a conveniently identified DNA fragment. Tissue samples may be obtained from hair follicles, whole blood, or the buccal cavity. The DNA fragment generated by this procedure is sequenced by standard techniques.

[0328] Other amplification techniques besides PCR may be used as alternatives, such as ligation-mediated PCR or techniques involving Q-beta replicase (Cahill et al, Clin. Chem., 37(9):1482-5 (1991)). Products of amplification can be detected by agarose gel electrophoresis, quantitative hybridization, or equivalent techniques for nucleic acid detection known to one skilled in the art of molecular biology (Sambrook et al, Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring, N.Y. (1989)). Other alterations in the disease gene may be diagnosed by the same type of amplification-detection procedures, by using oligonucleotides designed to identify those alterations.

[0329] V. Genomic Screening

[0330] The use of polymorphic genetic markers linked to the Gene 216 gene is very useful in predicting susceptibility to the diseases genetical linked to 20p13-p12. Similarly, as provided in Table 10 the identification of polymorphic genetic markers within the Gene 216 gene will allow the identification of specific allelic variants that are in linkage disequilibrium with other genetic lesions that affect one of the disease states discussed herein including respiratory disorders and obesity. SSCP allows the identification of polymorphisms within the genomic and coding region of the disclosed gene. Table 8 provides primers which one skilled in the art could identify exons which contain SNP's. Table 9 provides primers to identify the sequence change. This information can assist one skilled in the art to identify additional SNP's for use in genomic screening.

[0331] This method has been used successfully by others skilled in the art (e.g., Sheffield et al, Genet., 4:1837-1844 (1995); LeBlanc-Straceski et al, Genomics, 19:341-9 (1994); Chen et al, Genomics, 25:1-8 (1995)). Use of these reagents with populations or individuals will predict their risk for disease described herein including respiratory disorders and obesity.

[0332] VI. Treatment of Disorders.

[0333] Thus, the present invention provides methods of screening for drugs comprising contacting such an agent with a novel protein of this invention or fragment thereof and assaying (i) for the presence of a complex between the agent and the protein or fragment, or (ii) for the presence of a complex between the protein or fragment and a ligand, by methods well known in the art. In such competitive binding assays the novel protein or fragment is typically labeled. Free protein or fragment is separated from that present in a protein:protein complex, and the amount of free (i.e., uncomplexed) label is a measure of the binding of the agent being tested to the novel protein or its interference with protein ligand binding, respectively.

[0334] This invention also contemplates the use of competitive drug screening assays in which neutralizing antibodies capable of specifically binding the Gene 216 protein compete with a test compound for binding to the Gene 216 protein or fragments thereof. In this manner, the antibodies can be used to detect the presence of any peptide which shares one or more antigenic determinants of a Gene 216 protein.

[0335] The goal of rational drug design is to produce structural analogs of biologically active proteins of interest or of small molecules with which they interact (e.g., agonists, antagonists, inhibitors) in order to fashion drugs which are, for example, more active or stable forms of the protein, or which, e.g., enhance or interfere with the function of a protein in vivo. See, e.g., Hodgson, Bio/Technology, 9:19-21 (1991). In one approach, one first determines the three-dimensional structure of a protein of interest or, for example, of the Gene 216 receptor or ligand complex, by x-ray crystallography, by computer modeling or most typically, by a combination of approaches. Less often, useful information regarding the structure of a protein may be gained by modeling based on the structure of homologous proteins. An example of rational drug design is the development of HIV protease inhibitors (Erickson et al, Science, 249:527-533 (1990)). In addition, peptides (e.g., Gene 216 protein) are analyzed by an alanine scan (Wells, Methods in Enzymol., 202:390-411 (1991)). In this technique, an amino acid residue is replaced by Ala, and its effect on the peptide's activity is determined. Each of the amino acid residues of the peptide is analyzed in this manner to determine the important regions of the peptide.

[0336] It is also possible to isolate a target-specific antibody, selected by a functional assay, and then to solve its crystal structure. In principle, this approach yields a pharmacore upon which subsequent drug design can be based. It is possible to bypass protein crystallography altogether by generating anti-idiotypic antibodies (anti-ids) to a functional, pharmacologically active antibody. As a mirror image of a mirror image, the binding site of the anti-ids would be expected to be an analog of the original receptor. The anti-id could then be used to identify and isolate peptides from banks of chemically or biologically produced banks of peptides. Selected peptides would then act as the pharmacore.

[0337] Thus, one may design drugs which have, e.g., improved Gene 216 protein activity or stability or which act as inhibitors, agonists, antagonists, etc. of Gene 216 protein activity. By virtue of the availability of cloned Gene 216 gene sequences, sufficient amounts of the Gene 216 protein may be made available to perform such analytical studies as x-ray crystallography. In addition, the knowledge of the Gene 216 protein sequence will guide those employing computer modeling techniques in place of, or in addition to x-ray crystallography.

[0338] Cells and animals that carry the Gene 216 gene or an analog thereof can be used as model systems to study and test for substances that have potential as therapeutic agents. After a test substance is applied to the cells, the transformed phenotype of the cell is determined.

[0339] The therapeutic agents and compositions of the present invention are useful for preventing or treating respiratory disease. Pharmaceutical formulations suitable for therapy comprise the active agent in conjunction with one or more biologically acceptable carriers. Suitable biologically acceptable carriers include, but are not limited to, phosphate-buffered saline, saline, deionized water, or the like. Preferred biologically acceptable carriers are physiologically or pharmaceutically acceptable carriers.

[0340] The compositions include an effective amount of active agent. Effective amounts are those quantities of the active agents of the present invention that afford prophyladic protection against a respiratory disease, or which result in amelioration or cure of an existing respiratory disease. Prophylactic methods incorporate a prophylactically effective amount of an active agent or composition. A prophylactically effective amount is an amount effective to prevent disease. Treatment methods incorporate a therapeutically effective amount of an active agent or composition. A therapeutically effective amount is an amount sufficient to ameliorate or eliminate the symptoms of disease. The effective amount will depend upon the agent, the severity of disease and the nature of the disease, and the particular host. The amount can be determined by experimentation known in the art, such as by establishing a matrix of dosage amounts and frequencies of dosage administration and comparing a group of experimental units or subjects to each point in the matrix. The prophylactically and/or therapeutically effective amounts can be administered in one administration or over repeated administrations. Therapeutic administration can be followed by prophylactic administration, once initial clinical symptoms of disease have been resolved.

[0341] The agents and compositions can be administered topically or systemically. Systemic administration includes both oral and parental routes. Parental routes include, without limitation, subcutaneous, intramuscular, intraperitoneal, intravenous, transdermal, and intranasal administration.

[0342] VII. Gene Therapy

[0343] In recent years, significant technological advances have been made in the area of gene therapy for both genetic and acquired diseases. (Kay et al, Proc. Natl. Acad. Sci. USA, 94:12744-12746 (1997)) Gene therapy can be defined as the deliberate transfer of DNA for therapeutic purposes. Improvement in gene transfer methods has allowed for development of gene therapy protocols for the treatment of diverse types of diseases. Gene therapy has also taken advantage of recent advances in the identification of new therapeutic genes, improvement in both viral and nonviral gene delivery systems, better understanding of gene regulation, and improvement in cell isolation and transplantation. Gene therapy would be carried out according to generally accepted methods as described by, for example, Friedman, Therapy for Genetic Diseases, Friedman, Ed., Oxford University Press, pages 105-121 (1991).

[0344] Vectors for introduction of genes both for recombination and for extrachromosomal maintenance are known in the art, and any suitable vector may be used. Methods for introducing DNA into cells such as electroporation, calcium phosphate co-precipitation, and viral transduction are known in the art, and the choice of method is within the competence of one skilled in the art (Robbins, Ed., Gene Therapy Protocols, Human Press, NJ (1997)). Cells transformed with a Gene 216 gene can be used as model systems to study chromosome 20 disorders and to identify drug treatments for the treatment of such disorders.

[0345] Gene transfer systems known in the art may be useful in the practice of the gene therapy methods of the present invention. These include viral and nonviral transfer methods. A number of viruses have been used as gene transfer vectors, including polyoma, i.e., SV40 (Madzak et al, J. Gen. Virol., 73:1533-1536 (1992)), adenovirus (Berkner, Curr. Top. Microbiol. Immunol., 158:39-61 (1992); Berkner et al, Bio Techniques, 6:616-629 (1988); Gorziglia et al, J. Virol., 66:4407-4412 (1992); Quantin et al, Proc. Natl. Acad. Sci. USA, 89:2581-2584 (1992); Rosenfeld et al, Cell, 68:143-155 (1992); Wilkinson et al, Nucl. Acids Res., 20:2233-2239 (1992); Stratford-Perricaudet et al, Hum. Gene Ther., 1:241-256 (1990)), vaccinia virus (Mackett et al, Biotechnology, 24:495-499 (1992)), adeno-associated virus (Muzyczka, Curr. Top. Microbiol. Immunol., 158:91-123 (1992); Ohi et al, Gene, 89:279-282 (1990)), herpes viruses including HSV and EBV (Margolskee, Curr. Top. Microbiol. Immunol., 158:67-90 (1992); Johnson et al, J. Virol., 66:2952-2965 (1992); Fink et al, Hum. Gene Ther., 3:11-19 (1992); Breakfield et al, Mol. Neurobiol., 1:337-371 (1987;) Fresse et al, Biochem. Pharmacol., 40:2189-2199 (1990)), and retroviruses of avian Brandyopadhyay et al, Mol. Cell Biol., 4:749-754 (1984); Petropouplos et al, J. Virol., 66:3391-3397 (1992)), murine (Miller, Curr. Top. Microbiol. Immunol., 158:124 (1992); Miller et al, Mol. Cell Biol., 5:431-437 (1985); Sorge et al, Mol. Cell Biol., 4:1730-1737 (1984); Mann et al, J. Virol., 54:401-407 (1985)), and human origin (Page et al, J. Virol., 64:5370-5276 (1990); Buchschalcher et al, J. Virol., 66:2731-2739 (1992)). Most human gene therapy protocols have been based on disabled murine retroviruses.

[0346] Nonviral gene transfer methods known in the art include chemical techniques such as calcium phosphate coprecipitation (Graham et al, Virology, 52:456-467 (1973); Pellicer et al, Science, 209:1414-1422 (1980)), mechanical techniques, for example microinjection (Anderson et al, Proc. Natl. Acad. Sci. USA, 77:5399-5403 (1980); Gordon et al, Proc. Natl. Acad. Sci. USA, 77:7380-7384 (1980); Brinster et al, Cell, 27:223-231 (1981); Constantini et al, Nature, 294:92-94 (1981)), membrane fusion-mediated transfer via liposomes (Felgner et al, Proc. Natl. Acad. Sci. USA, 84:7413-7417 (1987); Wang et al, Biochemistry, 28:9508-9514 (1989); Kaneda et al, J. Biol. Chem., 264:12126-12129 (1989); Stewart et al, Hum.

Natl. Acad. Sci. USA, 87:3655-3659 (1990); Wu et al, J. Biol. Chem., 264:16985-16987 (1989); Wolff et al, BioTechniques, 11:474-485 (1991); Wagner et al, 1990; Wagner et al, Proc. Natl. Acad. Sci.

[0347] In an approach which combines biological and physical gene transfer methods, plasmid DNA of any size is combined with a polylysine-conjugated antibody specific to the adenovirus hexon protein, and the resulting complex is bound to an adenovirus vector. The trimolecular complex is then used to infect cells. The adenovirus vector permits efficient binding, internalization, and degradation of the endosome before the coupled DNA is damaged.

[0348] Liposome/DNA complexes have been shown to be capable of mediating direct in vivo gene transfer. While in standard liposome preparations the gene transfer process is non-specific, localized in vivo uptake and expression have been reported in tumor deposits, for example, following direct in situ administration (Nabel, Hum. Gene Ther., 3:399-410 (1992)).

[0349] VIII. Transgenic Animals

[0350] This invention further relates to nonhuman transgenic animals capable of expressing an exogenous or non-naturally occurring variant Gene 216 gene. Such a transgenic animal can also have one or more endogenous genes inactivated or can, instead of expressing an exogenous variant gene, have one or more endogenous analogs inactivated. Any nonhuman animal can be used; however typical animals are rodents, such as mice, rats, or guinea pigs.

[0351] Animals for testing therapeutic agents can be selected after treatment of germline cells or zygotes. Thus, expression of an exogenous Gene 216 gene or a variant can be achieved by operably linking the gene to a promoter and optionally an enhancer, and then microinjecting the construct into a zygote. See, e.g., Hogan, et al., Manipulating the Mouse Embryo, A Laboratory Manual, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. Such treatments include insertion of the exogenous gene and disrupted homologous genes. Alternatively, the gene(s) of the animals may be disrupted by insertion or deletion mutation of other genetic alterations using conventional techniques, such as those described by, for example, Capecchi, Science, 244:1288 (1989); Valancuis et al, Mol. Cell Biol., 11:1402 (1991); Hasty et al, Nature, 350:243 (1991); Shinkai et al, Cell, 68:855 (1992); Mombaerts et al, Cell, 68:869 (1992); Philpott et al, Science, 256:1448 (1992); Snouwaert et al, Science, 257:1083 (1992); Donehower et al, Nature, 356:215 (1992). After test substances have been administered to the animals, modulation of the disorder must be assessed. If the test substance reduces the incidence of the disorder, then the test substance is a candidate therapeutic agent. These animal models provide an extremely important vehicle for potential therapeutic products.

[0352] The disclosure of each of the patents, patent applications and publications cited in the specification is hereby incorporated by reference herein in its entirety.

[0353] Although the invention has been set forth in detail, one skilled in the art will recognize that numerous changes and modifications can be made, and that such changes and modifications may be made without departing from the spirit and scope of the invention.
